1. In addition to due based on when task starts, an option to have a habit appear as due based on when it was last completed.
   This could be a change to the Intervals option, or a new option. Another way to address it would adding a "defer" type option. When a habit is due, in addition to Yes, No, and Skip, "Defer" would push the habit into the following day, even in in the due day or interval it would not normally be there.

2. A conceptually related feature that could also be useful on its own, would be to see data of the amount of years, months, weeks and days since an item was last completed.
   I'd like it in the History tab, after the specific day and time. But, since it is a calculation that I want to automatically appear, not something the user needs to enter, maybe having it in a Reports tab makes more sense.

Basically, I want a way to have something due X times per week, month or year, at any day or time. I also want to see when I last did something. This is functionality found in so-called "countdown" apps; Up Ahead, Pinnings and LaxtTime are attractive and useful implementations I have seen, but how these 2 ideas are implemented in Strides doesn't matter to me, it's the functionality I want.
