Just a quick note about what has turned into a daily workflow that others might find useful.
I prefer to plan for the next day fresh while still having access to today’s list. I do not want Today items to carry over automatically. I mark those with a Tomorrow tag. A few lines of AppleScript that runs automatically in the wee hours on the Mac removes all Today tags, then changes all Tomorrow tags into Today tags. In the morning I have a fresh Today perspective ready to go.
