conceptional issue for caldav connections with many available calendars #215

I see a problem in my case since on my caldav server (Open-Xchange) I have access to many (around 40) shared calendars containing really a lot of data. When I access the caldav tree which contains all those calendars and start to sync it takes almost 24 hours to sync. After the sync is finished I can turn off the unneeded calendars in the calendar app but all data is already fetched which took a lot of time and likely consumes quite some storage. So if possible the adapter should first offer a list of available calendars to choose from because all of them are synced. (Please note that I'm everything but a caldav expert and I'm not sure if that is possible but I've seen it for carddav in another app.)

CalDAV clients receive a collection of available calendars on handshake and this behaviour is possible, however I haven't yet seen a client that supports this. Even Apple's Calendar starts syncing all of the data.

Any thoughts on this?
