An enhancement that I hope could be added at some point to the program: the standard select-folder dialog can become extremely tedious if you have to use it a lot. That's due to the need to locate the mouse pointer over relatively small targets and then click and click and click to move through hierarchies of subdirectories (it's easier, but still time-consuming, if it is done entirely via keyboard). I hope it could be possible to add an editable text field within all such dialog boxes, so that a path that has been copied to the clipboard can be pasted into the text field. There are a number of applications that have that kind of enhancement in their select-folder dialogs, and I really appreciate it when they do.
In Windows it's easily possible to copy paths of both files and folders by installing the free shell extension "Copy Path to Cliboard," which is readily available on shareware/freeware sites. It's also very easy for users of the command shell 4NT to do this (via echos %_cwd>CLIP:). Selecting a subdirectory by pasting its fully qualified path into a text field is an order of magnitude faster than doing the click/click/click "thing" in the standard select-folder dialog.
