Do any apps allow for controlling "blur NSFW images" on a per-account basis? That would be a killer feature for me.

In what way is this retro?

Awesome, it does. Handles a bit differently than Jerboa but I'm getting used to it. Thanks for letting me know about it.

I wish at least one of the apps would tie that feature to the account instead of having it apply to every account.

Do you want it to block every post from every user that is subscribed to that community?
