I made a small tool for exactly this annoyance on Plasma:
You want a different icon for one application, but you don’t want to switch your entire icon theme, and you don’t want to dig through .desktop files every time.
kAppIcon lets you:
Map a custom image, another app’s icon, or a single glyph from any installed icon theme (WhiteSur, Tela, Breeze, Papirus, etc.) to one launcher
Do it completely user-level (no root)
Batch-apply the same icon to multiple apps
Undo the last change
Create/edit icons with a simple pixel editor
See all your overrides and reset them cleanly
It’s built specifically with Plasma in mind, but works on other freedesktop desktops too.

This a colllection of videos that explores a variety of topics around creating scripts for the Mikrotik platform. It includes step-by-step lessions and tutorials showing you how to create your own MikroTik scripts.
The videos presented provide a hands-on, learn-by-example approach rather than being formal-training style presentations. They dip in to various scripting topics as we meet them using real-world scripting examples.
Up until version 6.49.8 (July 20, 2023), MikroTik RouterOS Long-term was vulnerable to CVE-2023-30799. Remote and authenticated attackers can use the vulnerability to get a root shell on the router.
MikroTik RouterOS comes with a default firewall configuration designed to provide basic network security. As a new user, comprehending these default firewall rules is essential to evaluate the initial level of protection for your network. In this technical guide, we will break down the default firewall rules and teach you how to interpret them to ensure your network's security is optimized.
Accessing the Firewall Configuration
To access the firewall configuration in MikroTik RouterOS, follow these steps:
Step 1: Log in to the MikroTik RouterOS Web Interface or connect via the Terminal (SSH or Telnet).
Step 2: Access the firewall settings by entering the following command in the terminal:
Interpreting Default Firewall Rules
By executing the above command, you will see a list of rules with columns representing essential parameters. Here's how to interpret the default firewall rules:
Column Headers:
CHAIN: Specifies the traffic direction the rule applies to (input, forward, or output).
SRC-ADDRESS: Defines the source IP address or IP range the rule affects.
DST-ADDRESS: Indicates the destination IP address or IP range the rule applies to.
PROTOCOL: Specifies the protocol (e.g., TCP, UDP) or all for any protocol.
ACTION: Determines what action the rule takes (accept, drop, reject, etc.).
COMMENT: Provides a description or comment for the rule (optional).
Default Input Chain Rule
The default rule in the input chain ensures the router itself is protected. It allows established connections (marked as "ESTABLISHED") to be accepted, so responses to outgoing traffic are allowed. It also permits related connections (marked as "RELATED"), enabling protocols like FTP to function correctly. Finally, the rule drops all incoming traffic with an invalid state.
Example Default Input Chain Rule:
0 ;;; defconf: drop all not coming from LAN
chain=input action=drop in-interface=!yourLANinterface connection-state=new
Default Forward Chain Rule
The default rule in the forward chain controls traffic traversing between different networks. It accepts established and related connections (similar to the input chain) while blocking any new connections from external sources to the router.
Example Default Forward Chain Rule:
0 ;;; defconf: drop all from WAN not DSTNATed
chain=forward action=drop connection-state=new connection-nat-state=!dstnat in-interface=!yourWANinterface
Default Output Chain Rule
The default rule in the output chain allows all outgoing traffic from the router to external destinations.
Example Default Output Chain Rule:
0 ;;; defconf: accept all from LAN
chain=output action=accept out-interface=!yourLANinterface
Enhancing Firewall Rules
To enhance your network security, consider adding custom rules. For example, you can create rules to block specific incoming traffic, allow access to specific services, or implement Layer 7 protocol filtering.
Understanding the default firewall rules in MikroTik RouterOS is crucial to assess the initial level of network security. By interpreting the rules provided in the default configuration, you can evaluate and enhance your network's protection as per your specific requirements. Take advantage of custom firewall rules, connection tracking, and Layer 7 protocol filtering to strengthen your network's defenses and ensure a secure and robust network environment.

At this moment I have to visit the community to use the UI to block, but some communities are so extremely nsfw that I don't really want to open them to block them. It would be very handy to be able to use the option for 'create report / block user' to also include 'block community'
I know I can also block communities in the settings, but the above mentioned option would be more user friendly imho.
For those of you who have invested in a MikroTik router, have you also incorporated MikroTik wireless devices into your network setup? What has been your experience with MikroTik wireless products? Are they a good choice in terms of performance, range, and reliability? Or would you advise to look for other vendors?
What made you choose MikroTik over other networking vendors for your home network setup? Was it performance, affordability, ease of use, or specific features that stood out to you?
I have a 1 Gbps fiber connection and want to maximize its performance, including IPv6 routing. Considering that IPv6 routing is not accelerated on the MikroTik RB750Gr3, should I still expect it to handle the load effectively, or would it be more suitable to explore other router options?
When it comes to home routers, do you prefer using the testing or stable firmware versions? Share your experiences, reasons behind your choice, and any noteworthy benefits or challenges you’ve encountered with either option.
Is the default firewall provided by MikroTik sufficient for home users, or should additional firewall configurations be implemented to enhance security? Share your experiences, recommendations, and any noteworthy vulnerabilities you've encountered.
Back To Home is a convenience feature, that configures your device for secure VPN access from anywhere in the world to your router and your network, even if your router does not have a public IP address, is behind NAT or Firewall.
Configuration can be done manually, or with our MikroTik VPN companion app (Android, iPhone (coming soon)).
If the VPN server (your home router) has a public IP address, the VPN app will create a direct VPN connection between the phone and the router. However, if the router is not directly reachable from the internet, the connection will be made through the MikroTik relay server. The connection is always end-to-end encrypted, the relay server or any other device does not have access to the encryption keys. In case of going through relay, speed could be limited.
This feature is a convenient option to access your home network or view content available in your home country, from locations, where some content is not available. It is not meant for anonymity, it is for simple one click access to your home network. For more granular security controls, we recommend to manually configure and secure a VPN connection using the advanced RouterOS options.

On 10/05/2023 (May 10th, 2023) MikroTik received information about a new vulnerability, which is assigned the ID CVE-2023-32154. The report stated, that vendor (MikroTik) was contacted in December, but we did not find record of such communication. The original report also says, that vendor was informed in person in an event in Toronto, where MikroTik was not present in any capacity.
What this issue affects: The issue affects devices running MikroTik RouterOS versions v6.xx and v7.xx with enabled IPv6 advertisement receiver functionality. You are only affected if one of the below settings is applied:
ipv6/settings/ set accept-router-advertisements=yes
If the above settings are not set up like in the example, you are not affected. Note that the vulnerable setting combination is not normally found in routers and is rarely used.
What this issue can cause: This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Mikrotik RouterOS. Authentication is not required to exploit this vulnerability.
Recommended course of action: You can disable IPv6 advertisements, or upgrade to RouterOS 7.9.1, 6.49.8, 6.48.7, 7.10beta8 (all versions already released), and of course newer versions afterwards.
