First, the idea is very good. Sometimes it is difficult to find a special version of a library. Unfortunately, I cannot download the libs with IBrowse 2.4. Maybe I`m doning it wrong? Click (or double click) on the icon does nothing.
I dislike the filenaming. Any reasons for it? Personaly I make it so:
<library name>_<version number> --> arexx.class_41.72
