// TODO: dh> make this an optional view (while also removing the "group" col then)?
//           It's nice to have, but does not allow sorting by priority really..
// fp> Yes, 90% pf the time, seing a grouped list is what we'd need most. (sorted by priority within each group by default)
// in the remaining 10% we need an overall priority view because a plugin is not in the right group or more problematic: in multiple groups
// BTW, when does the priority apply besides for rendering? I think we should document that at the bottom of the screen. ("Apply" needs an short explanation too).
// BTW, "category" or "class" or "family" would be a better name for plugin "group"s. "group" sounds arbitrary. I think this shoudl convey the idea of a "logical grouping" by "main" purpose of the plugin.
