Regarding #10, I have seen a lot of new folks get caught up on this. I think there’s definitely room for improvement in the initial goal settings. Instead of asking about extra safety days or however it’s phrased, it might need to ask ask both “Would you only ever enter integers as datapoints, or would you ever enter 0.3 units of progress?” combined with “What is the earliest day you want to be required to make progress on this goal?” and have it use those to set the initial settings.
Regarding #11… why?
Regarding #12, why are you getting so many emails? Are they “warn me x days ahead of time” (leadday) emails? Are they “you are going to derail today” (zeno) emails? Do you want the zenos bundled together? If so, do you only want the zenos with the same deadline bundled? Or do you just want the leadday ones bundled?
Regarding #13, you can enter times in HH:MM and it just works, assuming your goal is in hours. Once I found that out, I moved all my goals in minutes to hours and didn’t look back.
