1. Click on Select tool - prompt: Element Selection > Identify element to add to set
2. Hover on Space
3. Click on Edit Spaces tool - prompt: Edit Space > Accept/Reject Shape. Property Panel displays Spaces info.
4. Click on empty space in view window to accept per above prompt . Property Panel de-populates. User confused and tries again.
This is pretty klunky and could be fixed fairly easily. The prompt should read 'Accept/Reject changes'?
PS: populating the PP could be a little quicker.
