Description

I am doing a bit of bug-search in xfce in my free time.

Sometimes before submitting a but I want to check if the bug is still present in the master git HEAD.

I don't really want to make a package reinstall it every time I want to test some version of a package. It's cumbersome at best, and becomes a genuine pain when doing a git bisect.

Would it be possible to add an option (ideally a gui button in the "Add new items" window to load panel plugins from files?
