Just to keep things separate:

Citing @BigAlanM from #12:

I'd like to see the layers check list stay open until it loses focus rather than having it close every time an option is toggled. I realize that if I were to learn the hot keys this wouldn't be a problem but I've yet to print out a screen capture of the menu.

Citing my answer:

I do understand your request about the layers menu. However, I am not sure whether the GUI framework we use supports it. To me, this is not a bug, but a feature request, so I will not be able to look into it in the near future.
