Working through this myself. I’m leaning towards #context/errand, #context/home and then @context pages such as @errands, @home.
The fastest way to access these is Ctrl-O, @...
I have a embedded query on each which is (line:#context/home) -@home, with the page itself excluded otherwise it turns up in the query.
What I not yet managed is to have it exclude to do items already checked off.
