Ok, got it now. I’ve been trying to use the default workspace as the basis for the app badge count. I edited my default workspace, and set tag filters, but did not actually save it as a new, named workspace. If you don’t do that, you can’t select the “unnamed” default workspace as “default” (if that makes sense).
So I saved the default default as “home” with all my filters, then set “home” workspace as the default. This solves my problem. Thanks so much!
I still find the Manage Workspaces screen to be a bit confusing. The bottom half shows my saved workspaces, including my new “home”. The top half shows the built-in default workspace, which now is essentially the “home” space. It would be less confusing (to me) if the default workspace at the top took on the name of the saved space that it essentially is.
Having said all that, I’m thrilled that I’ve got it working like I want. @agiletortoise, Drafts is still the most important app on any of my devices!
