Usually when I add a new space, or when I’m duplicating an existing one, the first thing I want to do is to give it a meaningful name. Especially in the case of duplication, I will immediately want to assign a new name to avoid two spaces having the same name.
Suggestion: after clicking
+ Add or
+ Duplicate space, automatically select the space name so I can type in a new one without mousing and double-clicking. Even in the case of accepting the randomly-generated name, it wouldn’t hurt to select the name. I would be clicking away from the dialog anyway.
