See the initial portion of this thread - I use it to have certain windows be and stay open.
Basically when you “view as text pane” - Cmd-Opt-X (and in general, if you “tear away” a pane), it stays consistent and doesn’t change even when you hop around your project. The windows will reopen on restarts too.
I would just make aliases of the Notes I need and drop them in a Container, then change the view of that Container as needed.
The result of your Agents are in the form of Alias Notes within the Agent’s Container. So you can set an Agent to look for an Attribute value like “Essay on GeoPolitics" or set a Boolean User Attribute “ActiveEssay” or…. (the idea being to collect the results in the Agent’s Container) and go from there. The same applies to your prior question, you can roll these into one.
