Add generic CalDav Calendar syncing
I corporate environments there are many other calendar server systems we are forced to use, and CalDav is well supported standard for talking between clients and servers. Being able to use TheBrain calendar as the interface for managing those calendars would be a big plus.

Yes. All these requests to support e-mail program X, or Calendar Y, could be solved by supporting CalDAV and CardDAV.
