You can already make your avatar a gif, press on Rhythmically's name above and you'll see the little box pop up and that's when you can see it move. If you press and go to their completed profile, then you'll see it move still, too! As for making gifs move when viewing threads, I'd say just leave it off and keep it still, there's no real point, but I guess a disable option in preferences isn't too bad of an idea - depends how many people would want it.
The poll does look quite promising, I didn't expect that turnout I guess if it was there with a preferences option then it would appease both the people that want it and also the people that don't!
Only if there is an option to disable it. I find it annoying like seeing a laggy ad on the side of your screen.
Exactly, so why not be able to turn off .gifs in avatars then? According to the poll so far, most people would want that, and the people that dont, can just turn it off.
