With the new update I have one issue that gives me trouble. I used to set the armor status to Bottomcenter and the xOffset to -120. That perfectly placed it left of the bar. With the new version only values >0 are allowed so there is no way to place it left of the center.

And a suggestion. The damage values for tools is so different that I find a percentage color is not the best way to color the damage value. For example I don't care if my tool is 20% 50% 64,4% or 100%. But I care if it goes under 50 uses. With diamond set to 10% I have 150 uses left with iron I have only 25 uses left! It's very easy to miss the 25 but I dont want to repair a tool with 150 uses. So a absolute value for damage coloring would be nice.
