 	--if trait timer completes on another char, the trait goes green, but the icon remains the hourglass.
 	New Feature
 	Add a button to put it in relative mode.
-		Provided you have one other char in there (it is disabled for #all and the current player), it will show the traits that the current player can make (or will be able to make if still in research) that the selected char doesn't have. This is for when you are trying to consolidate traits on to your main crafting chars, to get that magical "8" traits known. If you are like me, you might get alts to learn traits because you don't have the bank space to hold the item..

+	New features
+	If using the relative mode but the destination character is already researching that item, the icon will be a dull red tick.
+	Characters can only research 1 trait in a item at at time, no matter how many research slots might be available.
