Folder sidebar size
The folder sidebar should be adjustable, I can't see the folder names sometimes and want it to be bigger.

I'm in full agreement with all of these
Second for making the width of the sidebar adjustable. As a Yahoo Mail Pro user I sort my emails by various folders. The existing fixed-width sidebar truncates the names of all the folders making it very difficult to identify them.
And, add the ability to hide it completely so the message pane can be larger, please.

Make the width of the sidebar box adjustable. I can't make it wider to read the full title of folders I created
