I didn't see it on the feature list, but it might be nice to allow it to run as a cron job and send email for reminders. These days, most mobile phones have an associated email like [email protected] (depending on carrier), so you can send yourself text messages about chores and whatnot.

Or, perhaps just as good, have a way for it to dump out data as json, and could be consumed by some other send-the-email tool. There is the "-json" sqlite option, of course, but I'm not sure if your schema is meant to be stable.

I have a perl script for reminders like this that has been super handy over the 10+ years I've been using it. Never bit the bullet to put it in a nice UI or have a backing DB like this project, though.
