I also use middle click a lot and it was only the button functionality. It didn’t fully break but became very inconsistent. (Sometimes doesn’t click, sometimes clicks twice in a row). Now I have to use ctrl click. Sucks for programs where middle click drag moves the view around.
Man I wish we had a “flag” option as an alternative. I don’t wanna block anyone because sometimes I still wanna read their comments/posts.
I just want to flag them so when I come across them again I can keep in mind that they did a no-no before. You could even use it to categorize (this user is a spammer, this one a troll, etc.)
