Remember mute setting on video playback:

When playing videos, it always starts with audio turned on (on iOS at least).

Ability to remember user's audio mute choice from previously played video will be nice.

Searching:

There is no way to search in clans so I don't know if anyone has already reported this or not...

Swipe to upvote/downvote:

When you swipe twice on a post to upvote/downvote, it doesn't undo it. It should undo your action.

Preview in Text Post Editor:

I see a few formatting options and markdown support in the editor. It'll be nice if we can see a preview before posting.
