I'd love to see an addon that doesn't change the way buffs or debuffs or shown, but simply lets us move debuffs around the ui layout in exactly the way we can move buffs.

I don't mind the default buffs ui at all except that we can't separate debuffs from it. Ideally this would be something that Trion would work into their ui, but an addon would work too.

Currently the best buff/debuff addons seem to cause significant system slowdown, so an extremely simple separator would be a godsend.
