I would like to remove ability for users to have animated GIFs as avatars. Disallowing the .gif extension would be the easiest way I think, but I cannot find the setting in AdminCP anywhere.

Also, there seems to be no setting as to how big (in kB or in size) the avatar may be, or at least I could not find it.

Could someone help me find these?

Also another question. When doing updates (like 4.0.1 that was just released), these also update the main official theme code and CSS. I have created a copy of the official theme and made my own custom changes to it. Will my copy receive the fixes included in the update, or do I have to make a new copy every time there is a patch and re-do all my custom changes?

I got the exact same question... All these avatars are small again :0
