Workspaces
I've been reading up on Workspaces, since I will evidently need to send mine along with my barbershop template. I wanted to see which elements are configured in my Barbershop workspace, to see if I needed to add anything, or change what I had. Evidently, you can no longer edit an existing workspace. In the older versions, you could go to View > Workspaces > Edit. In 4.5, you get View > Workspaces > Configure. This brings up the Workspace panel, showing your spaces, and you can create a new one, but not edit an existing.
A giant leap backwards? Or, again, did I miss something?
