One annoying thing about FreeRapid is that it has plugins for tube and images sites that can only be disabled one-by-one. I bet most people don't want plugins for images hosts enabled.
There should be a way to disable all sites of a category.

Unfortunately plugins are not distinguished by type; they all have the same internal representation.

A workaround could be to disable clipboard monitoring (e.g. by clicking the icon in the status bar) when you don't need it.
