Adjust the width of the Folders panel on the Documents tab

On the Documents tab on Projects/Tasks/Issues, you can collapse or expand the Folders panel on the left side of the screen, but you can only expand it to a fixed point. We would like the ability to adjust the width of that panel to accommodate the long names of some of our folders. When using the Folder panel to find the folder you're looking for, you can hover over the folder to see a tooltip with the full name, but that is not nearly as efficient as being able to just view more of the folder names on the screen.
