Handwritten annotations vs highlighting

I’ve taken the habit to annotate all my readings on an e-ink device (onyx boox max lumi, an android device). (In my experience, I have far better memory of what I read if I annotate stuff, and remembers way better my hand drawing than the actual text.)

Anyway, the issue is that those annotations are incompatible with the selection of the text for highlights.

bug

I believe that having the annotation as a bottom layer (putting the text forward) might be a solution?

Does any one of you, has an idea (1) if that would solve the problem? (2) how to go about it? (3) ever better : a workflow that incorporates handwriting and highlighting.

thx
