IdStory Identity Manager

In my environment I have more than 50 "top" folders in catalog. Some of them have it's name longer than 25 characters. In the modal for role selection from a catalog the column for the folder tree is too small. A horizontal scroll bar is show and the "Select" and "Cancel" buttons are down bellow the whole tree - the user also need to scroll to click on them.

Please improve this modal to be more comfortable to use when we have more complex role catalog, longer role names, etc. May be add some responsibility or allow the user to change a size of the modal.
