Instead of hiding offline members, just truncate sidebar members at 100 people

It is very annoying in my private channel of 20 people to not be able to see who is a member of the channel. I literally have no idea who has access to some channels now.

You say that this is for performance reasons.

Well servers that have 10,000+ members still show thousands of online members in the sidebar. That can't be good for performance.

So why not just show 100 members, offlline or online, per channel. That way in private staff channels I can still see everyone that's involved. And in bigger channels, who cares.
