These are electric nail "clippers".

Though it's really more of a nail shaver if you think about it....

Red is bad and blue/green is good.

The colors are backwards and it bothers me constantly. Is there no way to change those?

My own name is highlighted red. I don't even like the color red. I want my own name to be highlighted in green.

I would pay money for this functionality it bothers me so much.

It's a metal band tensioner and cutter. Usually used to secure something to a post that you have no intention of removing for the foreseeable future.

Obviously I understand the trash can icon, but I didn't delete my own comment so is that telling me the mods or the original poster deleted my comment? Does the symbol on the right mean they blocked me?

I tried finding info anywhere in the sync app and looked for Lemmy FAQ pages but none of them had anything on the symbols anywhere.
