For context, I have built an web-app reminder-app that run locally on the machine, uses node and express see the project at https://github.com/priyank-p/reminder-app.
Currently some of its features I can mention are:
* It reminds you of due reminders with web push notifications.
* It can automatically startup when you start your machine.
* It supports markdown for reminder content.
* It can be added to homescreen, after which it almost feels like native app.
* And, is totally cross-platform.
Apart from those, I have started working on cross-browser extension so you can quickly add reminders.Is there any other productive feature you can add to the app?
