There is a settings folder with and xml file. Open that with an xml editor and take a look at the settings you can change. There is an option for background A,R,G,B
I am not 100% sure what they each do.
This is the settings upon downloading.
Code xml
<backgroundA>190</backgroundA>
<backgroundR>0</backgroundR>
<backgroundG>0</backgroundG>
<backgroundB>0</backgroundB>
Try change one of the numbers and then save + reload plugin and see if that puts a colored background behind it.
I’m not 100% but if it works like windower console
A= alpha/transparent (no background)
R = red
G = green
B = Blue
The max number u can use is 255.
Just for reference your text will be
Code xml
<textA>255</textA>
<textR>255</textR>
<textG>255</textG>
<textB>255</textB>
So make sure you don’t use the same color as that. hope this helps.
***EDIT***
try changing it to
Code xml
<backgroundA>255</backgroundA>
<backgroundR>0</backgroundR>
<backgroundG>0</backgroundG>
<backgroundB>0</backgroundB>
I think that would mean 0% transparent (black)
