- view attachments (even though I know it's still a labs, but it would be very useful);
- see my other calendars, that is if I create another calendar with my Google account I see the events only if I go in my account, but I don't see in my site the events created in the new calendar;
It would be perfect if also these two option would run, so I could use Google calendar in the best way.
Attachments are not included in the google API so there is no way to get them.
Just add your second calendar to GCalendar and you will have it included in GCalendar. Too bad you didn't ask in the forum, I'm sure we could help you!!
