Give the option to hide voice users in collapsed text/voice channel folders

The reason I collapse a folder is frequently because I don't want to see anything in it. When you're part of one of the large multi-gaming community servers or other large servers there can be many folders with many voice channels that you aren't interested in and yet the entire interface is taken up with showing the avatars of users in these collapsed voice channels. This is really annoying, especially on a phone, where I might have to scroll through 3 pages of avatars just to get to the actual text/voice channel I care about.

It would be really nice to be able to hide voice channel users in collapsed folders. This could be either in general or on a per folder basis (similar to muting).
