Maybe I'm missing it and it's already there somewhere, but it seems like there should be a way to see the total number of minutes in a routine. For example, I'm trying to set up a routine for my workday that spreads my energy around to the various projects I need to work on. I want to set it up so the whole routine "controls" the six hours I spend "working." I've set up the activities I want to pursue, but now I'm trying to establish the duration of each. There should be a way for me to either a) see the total duration for the routine, or b) allow the user to set a total duration for the routine, and then, as I change the duration of each activity, have that activity duration deducted from the total -- this would let me know how many minutes I have left to "spend" on the remaining activities.
The first one is probably easier to set up, but the latter might be more "fun" to use :-)
Anyway, that's my idea.
