As mentioned above - this system works extremely well for me. I tried to use a bunch of the more advanced features in Things in the past (such as tags and projects) but they just add complexity and don’t provide value to me. So I kept it as simple as possible - which seems to work best for me personally. Give it a try if you are intrigued (you can get a trial version of Things which is fully functional for two weeks or so - enough time to try this out). And let me know how it works for you.
