I am aware that you can rename a space by opening the pull-out menu on the top left. I feel like it’s a bit hidden and lots of students miss it. This results in lots of spaces called “Space”.
A suggestion would be for the default name to be something like “Unnamed Space” and clicking the name at center top would allow you to set the name, in a similar way to naming in Google Docs.
P.S. Is this a suitable place to post feature suggestions?
