allow deleting the directory you are in
When deleting a directory, it's good to know you aren't deleting stuff you didn't mean to. Right now, in order to delete a directory you need to navigate out of the directory to the parent directory and then select the directory you were just in and delete it (making sure not to accidentally select and delete a different one). It would be a better workflow (when no files are selected) to be able to go to "Edit->Delete Current Directory" or right click in the white space of the view and choose "Delete Current Directory". After deleting the directory, the view should be navigated to the parent directory. This way you are sure what you are deleting because you can see the contents of it. Windows 2000 had the ability to delete the directory that you were in and that's the only remaining feature from that silly operating system that is missed in modern times.
