In leap, there is no gnome-calendar, so to manage calendars we have to install Evolution.
California is offered is some unofficial repos, but this is a deprecated / unmaintained application. I took the source of gnome-calendar and compiled it, but I am stack with an old version because of unmatched dependencies.
And this old version does not allow to configure calendars (no goa integration).
So to avoid all this hassle, it would be nice to have gnome-calendar provided by default.
Thank you in advance,
