It would be cool if the memory could be randomly generated on a daily basis rather than on page load. So that I could make a daily habit of reviewing a memory or not worry about when I see an interesting memory, needing to view it now vs at some point today.
Just the random memory popping up every time I open the app is a little much, but to have a single highlighted memory daily, which pops up once daily, and then sits in the dashboard for the rest of the day to remind me to review it, would be a lot more practical. And also, if the view in the dashboard would change to indicate that it has been reviewed, that would be cool.
For extra credit, track the daily review of memories over time, like in the game statistics, though it doesn't need to be part of the game.
