Synopsis: 'Plugins' window should be resizable
Bugzilla-Product: dia
Bugzilla-Component: general

Description:
Some of the contents of the 'plugins' window
does not fit in the window, and one has to scroll.
This might not happen on different systems with
different fonts, but, in general, windows like this
should be resizable and there doesn't seem a good
reason for it not to be.
