First off, I love the work y'all are doing.
But, I've found a few problems.
1) You can't select to use no implement for a power. I know it sounds odd, but you actually don't need to use an implement for implement powers, but you get a bonus when using magic implements.
2) I can't figure out how to do a Dragonborn's breath, since it too doesn't use an implement. Since all of the attack bonuses use implements/weapons, but the Dragonborn's breath doesn't use either, I can't figure out how to make it work on the attack's tab.
3) Weapons automatically apply the proficiency bonus without checking for actual proficiency. (I know it's odd, but I've got a dragonborn warlock that doesn't use an implement but does use a halbred without proficiency). I'm adjusting it with a -2 misc. penalty, but I would have thought it would have been smarter.
4) The power menu on the attack tab has two versions of powers on it (my 1st level DB Lock has two versions of all his class powers on that dropdown menu).
