Block highlighting very difficult to see

The block highlighting feature is potentially very useful. However, for me, the highlighting is very difficult to see. I have modified the background color of the editor, but that has not helped. It would be great if the contrast of the highlighting was increased, or adjustable by the user.

Yes, I agree, this is a regression from Script Debugger 7’s implementation of this feature. We’ll try to improve things.
