There is a *very* annoying usability problem with
the "add jar/folder" button in the library
manager. Because you allow the selection of
directories, it is impossible to enter:
"c:\program files<enter>" in order to quickly
navigate to that directory in order to choose a
JAR file. By splitting up the button into two
separate options, you can have the JAR chooser
expect only files (not directories) and this will
allow better keyboard navigation. Currently it is
an absolute nightmare to enter JAR paths using the
file-chooser. Using the mouse is too slow.
