This was an early purchase for my Playdate and I still love the idea and execution of it.
This may be an unrealistic idea, but what if there was either a kanban-style view of to-dos or a separate tab entirely dedicated to it? It seems like it could be intuitive to shuffle cards between columns, and the aspect ratio would complement that sort of thing.
I think any kind of feature that leans into the idea of the Playdate's potential as a stationary, always-on desktop display will only add to the practicality of this app.
Looking forward to any future development!
