Thanks for your answers... I've been trying it today. It looks great and it integrates perfectly with RC. The one from MyRoundCube plugins has its own icons, I don't understand why, but as Sebastian says CalDav is a necessity.

We'll keep waiting...

Hi,

...

...

Is this a new plugin? It looks great...

It's written by Roundcube developers for Kolab Systems. It has driver-based backend and currently supports SQL and Kolab backends.

are there any plans to provide a CalDAV backend for this calendar?

Thanks, Sebastian
