I like this idea. When I did Bullet Journal I ran a few lists that had a similar function. I had lists for:
- thisweek
- nextweek
- thismonth
- nextmonth
I'd migrate tasks between the lists and when it came to planning I'd look at #thisweek and arrange the tasks into the week so that everything got done.
As I'm looking at new task managers and do versus due (watch tomorrow for that discussion) tags like this will be crucial.
