Treechat feature request: on the browser user interface I can see two arrow buttons on the top, one left, one right for navigating through the different threads.
In the middle there is the closing button [x], but only when scrolling to the top.
The other two arrow-buttons are always there.
In my opinion having the closing [x] button there all the time as well would be convenient.
So you do not have to scroll up for closing a thread, which sometimes can take quite some time.
