This would be great. It would also be great if we can remove/hide the defualt "Chats" section. As soon as I begin creating my own sections, that one is not necessary.

A step further would also be to be able to hide Replies, Posts, FollowUps, Activity and Drafts & Sent. Right now they take up a lot of space, and I know for myself, that I won't be using the FollowUps feature, so that one won't be relevant for me.
