I think the context menu is fine, and adding it should not be an issue
now (I could say not being able to readily use my data is a bug, and
your suggestion fixes it).

great, thanks

yes - I tried, but the newly added polygon etc is not displayed once
digitized. Oh, now I see: the custom grass symbology prevents me from
seeing it. Once moved to single symbol, it is displayed.

I can imagine. Where do I find a guide on how to digitize? I tried
adding polygon, then centroid, but I only ended up with an invisible
geom. I'm certainly missing something here.

All the best, and thanks again.
