I created a "task" for myself that was mostly a reminder to take breaks and relax today on a day that had a bunch of stuff and I'm also about to leave on a trip. Keeping it at the top of the list meant I had a nice reminder pop up every time another task was done - it was great! But then I have to go back home and move to the next task. Got me thinking that being able to add something like this and have it pop up whenever the next task comes along but not interfere with the next task would be a lovely feature.
