Right now, IMCE mkdir adds a single button to the top of the IMCE dialog to "Manage Directories."
When clicking "Manage Directories," a dropdown appears to either Add a subdirectory or Remove a subdirectory.
When removing a subdirectory, the user must type the subdirectory name in the text field.

My Proposal:
Instead of the single "Manage Directories" button. Add two buttons: "Create SubDirectory" & "Delete Subdirectory"
When "Create SubDirectory" is clicked, a dropdown appears to enter the new SubDirectory name & click OK (very much like it is now).
When "Delete SubDirectory" is clicked, a dropdown should appear to confirm the directory deletion. The current, active subdirectory is deleted (deletion of root directory & deletion of non-empty directories with used files should not be allowed). IMPORTANT: No need to input the directory name. The CURRENT ACTIVE directory is the directory deleted.

Is this proposal possible?

P.S.
Thanks for the GREAT family of IMCE modules. They are the closest thing in Drupal to user-friendly file management solution.
I am REALLY interested in IMCE & the FileField sources module. With just a few tweaks & updates, IMCE + FileField Sources will be the ultimate in Drupal file management!
