You might try making up one list. Dividing it into 2 (or whatever), labeling for whatever time you need. Any modifications just place them on the list. And keep Stickies open.
You know, the problem I have with Things 3 (besides it costing a whopping $50 for the Mac with no extra features) is I forget to look at it! So I get all backed up. I still input a lot but I don’t really use it the way I should. When I actually open the app, I spend my time deleting old stuff.
Maybe I should email myself daily. So maybe some smart developer or Mac nerd can tell me how to do that.
