I think I’ve said this before but:
- Remove the radio button for changing active layer. There just isn’t any reason whatsoever to change active layer, instead this just fools new users into making mistakes. (If there is any valid reason for anyone to change the active layer in any use case that could easily be handled from an extension.)
- Rename Layers “Tags” or "Visibility tags as they don’t define isolated lockable drawing contexts which is what layers do in every other program using layers I can think of.
- Rename Layer0 “None” as it’s not really a layer. It cannot be renamed or deleted.
I can see how some people would be quite reluctant to point two and three given it would require a lot of documentation help articles to be rewritten. The first point however should be easier to implement.
