Hey. Sometimes I have ideas.
Erm... I'm gonna have to double-check that. But anyway.
Since the displaying of the activity is a client thing (you know, you can hide replies with Stylish and such), it could be possible to have a toggle thing that puts the activity back in its old state.
So.. like... the default one would be the state where every comment gets bumped if someones replies on it, but you could toggle this option if, like me, you find the classical way more practical to use.
Again, I don't know shit about how the coding of the forum thingies are made, so I'm basically asking for something that I don't even know if it is possible or not, but hey, might as well try.
Yeah, my propositions are useless.
This post lacks ponies. There we go, now it's relevant.
