I really don't know how this "sharing" works ... do you have any technical documentation or hints about this feature? If it is supported directly by DAViCal we can add it, but if it is "hardcoded" into Agendav database, then there is no way to add it (our client is pure JavaScript).

Currently we support only sever-side color (stored as dav property) and we have plan to add support for editing it. The main problem is, that if we add support for server-side color management, I have no idea how to not confuse users with another "local color" management.

> - Permit users to include external calendars ( .ics ) directly via caldavzap web frontend. Actually it seems possible only via config files.

It is not possible in pure JavaScript ... the server where the .ics file is stored MUST returns proper CORS headers and this not true for 99.9% of servers :-/
So the only way to share .ics files is usually a local proxy (and it must be set by the server administrator).

Will add in future.

There are major changes in synchronization in the upcoming versions of both clients. These changes allows you to use much smaller sync-interval without affecting the server performance. Personally I don't want to allow users to perform manual synchronization, because if you have lot of stupid users then they can DDOS your server by clicking to "reload" every few seconds (experience from real environment). So currently there is no plan to add manual refresh option, but if we get lot of request to add this feature we will add it.

p.s.: feature highlights from the next versions:

CalDavZAP:
- major synchronization changes - instead of N (or 2N in worst case) requests we perform only 1 (or 1+N in worst case) requests [N = number of collections, worst case = there is at least one change in each collection]
- support for time-range synchronization (only limited number of events are downloaded, the rest are downloaded if you click to future or past) => MAJOR performance improvement
- minor GUI changes

CardDavMATE:
- major synchronization changes - instead of N (or 2N in worst case) requests we perform only 1 (or 1+N in worst case) requests [N = number of collections, worst case = there is at least one change in each collection]
- support for simultaneous collection displaying
- major GUI changes (e.g.: addressbook colors)
