Hey there, I found my C-fu is pretty limited and I could not dig enough to replicate to the other modes. I only know the theory and the documents, but I would need to invest in a third party dev to work it for me. I have it queued for later, but for now I’m working on getting some funds for the devs I know (as I like to sponsor them directly). It should be possible, it’s all overlay code, but it’s only tied to one method of drawing - yet it’s an overlay type of drawing. Meaning… it could be just added as a feature to the other drawing modes.
TLDR. It could be exposed as overlays to the other modes - technically. From what I researched. I just… can’t do it myself. I just… know where the code for it sits really.
I think the biggest hurdle is the UI entry design to toggle it for the other modes - deciding the UX at the end of the day.
Another hurdle is how the theming works, you’d have to re-write some wireframe theming systems for it to be possible, so it’s also in those documents.
