It would be nice to control the highlight of the fill independently from the linework, similar to InDesign. For example an opaque border line with a fill set to highlight. Currently both the border line and the fill highlight.
I know there is a work around to copy / paste in place the markups on top of each other. Setting the bottom filled markup to highlight and leaving the top markup as opaque, but that makes future editing of the markups time consuming and it's annoying.
Please consider making this a new feature.
