I'd like there to be the option to set a postpone "pool" of minutes. So for example, if I set a pool of 60 minutes, when I postpone, I can choose up to 60 minutes, but whatever I choose is removed for use for the rest of the day.
Also with it, I'd the ability to end the postpone early and regain any "unspent" postpone time. This would allow me to overestimate the time needed, then adjust if I finish early, rather than having to constantly be interrupted by postponing 5 more minutes, in fear of losing time I didn't actually need.
