Simple Suggestions

Hi, I have three simple feature suggestions.

1) Locking Channel Movement.
As a server admin, I can move channels by simply dragging them.
It is really easy, and that induces a small problem.
I often unintentionally move channels (change orders).
So I think it will be better if there is a feature that can "lock" channel movements so that I can move channels only when the "lock" is off.

2) Locking Server Movement.
This is quite similar to 1). Moving discord servers is also very easy, and it induces the same problem that I often unintentionally change the order of servers.

3) Folding Roles in the Member List Sidebar.
I know that server admins can decide whether to show certain roles or not in the member list sidebar.
As a member, I think it will be very great if there is a feature that each member can decide whether to "fold" or "unfold" certain roles in the sidebar, which is very similar to "folding" categories in the channel sidebar on the left.

Thank you!
