Requested feature overview description.
Currently you can add posts to sets from the post options, but you cannot remove them from there.

Why would it be useful?
I've accidentally added posts to the wrong set more than once, because of how the sets default to the one that was last used. So it tends to get mixed up when I'm working on several things at once in multiple tabs...

Being able to easily remove those would be helpful.

What part(s) of the site page(s) are affected? https://e621.net/post/show/

"Remove from set..." is in the post options. It's below "Add to set...".

I don't see it anywhere on post #333673. Maybe you are thinking of the post index, not post pages.

Uh, no it isn't?
The next option is Add note/translation.

Damn, I was looking at the wrong page. Nevermind. +1
