Additional Skill Panel Filter

I'd like to propose that a "Campaign" filter be added to the skill panel.
Once you've begun to unlock a large amount of skills from multiple campaigns, it becomes difficult advising people on builds if you don't know what skills they have available to them

Also, has anybody else noticed alphabetical inconsistencies with the skill panel recently?
Things like Lion's Comfort appearing at the top of the list of Strength skills, etc.

Edit:
Oh, and an Elite / non-Elite skill filter would be nice too.

You can already sort skills by campaign...
ok it's true that they're not alphabetically arranged but still.

lol, well I never.
Learn something new every day, eh?

How about this for an additional filter? The ability to collapse an entire attribute. On my warriors, I never use hammer mastery, so if I could collapse it, it'd save space and serve to streamline the interface.
