XP at %00.00 instead of %00.0?
 

Is there a way to get the game to display in 100ths of a percent? All I see are Xp bars displaying like 43.5%. Is there a way to make the game display 43.54%?

No... or not directly. The DynamicData is only sent in 1/10 of a percent increments.

On thinking about it, however, you might be able to set up a script to convert the gauge's Progress value to text, which would give you another digit, but you'd have to hover over the window...

OnHoverIn="ExpBlueText.LocalText=((ExpToNextBubble.Progress)*100)"

I don't have the ability to test this at this time.
