0.22.1
BetaYour plan's profile limit now shows before you build a profile, not after you save one.
The limit is visible before you spend time on it
If your plan's profiles are all in use, the Profiles page now says so up front: New profile is switched off, and a locked slot sits under your existing ones showing what the next plan up includes.
Before this, nothing stopped you opening the builder, naming a profile, choosing its connections and picking its tools. The limit was only mentioned when you pressed save, by which point the work was done and there was nothing to do with it.
The same panel now appears if you open the new-profile page directly, and it links straight to your billing page if you are the account owner. If you are not, it says who to ask.
