Anyone who has an answer to this question?
I find two other threads about this, but with no satisfying solution, only workarounds.
I cannot change the color, cannot make it bold or underline it (Font: set by style).
Cannot change border / schadow Intensity (Layout: greyed out)
I even cannot add Special Icons in tab Caption.
When looking at mentioned two threads, more people are searching. There has to be a way to remove the "set by style" I guess.
