EteSync Integration
Evolution has recently added built-in integration for EteSync. EteSync is an open source end-to-end encrypted service to sync and store calendars on the cloud in a secure and private way. It would be very nice and user friendly to have this built into GNOME Calendar were all you need to do is login to your EteSync account and your calendars are available inside the app.
If this feature is added, please allow for multiple EteSync accounts to be added and not only allow one account and to allow self hosted EteSync servers to be added also.
