Reminder UID column needed for CalDAV integration. Most support long strings.

Add a UI page and database table for tracking reminders added, edited locally; pushed or pulled remotely

See if it can be broken

allow edit of upcoming reminders

Add Calendar ID column (ID string). Add/edit screen should list available calendars in drop-down.

Options:
#1: Add a calendars table (?): Cadence User ID, CalDAV host, Calendar ID, CalDAV user, CalDAV pass. Con: I don't want to create an app that is responsible for anyone else's password(s).

#2: Require that the calendar be a local Radicale instance with matching user ID and password? Con: Too inflexible? At the very least, requires some thought on how to secure Radicale properly.

#3: Require the CalDAV host(s), username(s), and password(s) to be set in a config file. Assumption is that only users who are self-hosting will get to have integration.

Test CalDAV integration with Radicale. Test file import/export to local instance as well as sync over HTTP.

Examine apache logs for warnings, other noise

Offer the option to delete account and all data for logged-in user. Put the onus on the user to take their own regular backups (it's a reminder app, so that shouldn't be hard!) so that if they choose to delete their account, the hosting service will not have their data in backups. So, that's really three things:

1. Provide means of bulk export/import
2. Inform the user to export backup (explain privacy and backups on a "help" or "about" page)
3. Provide means of data deletion (offering option to export first)

Add search capability

Add hyperlinks in notes?

A natural approach to syncing with local Radicale; necessary for backing up data before testing and for portability/privacy.

Script needed to migrate v1 data to v2 table

What market for Cadence would exist based on this feature alone? Get recurrence right on iOS reminder app.
