Tasks and Calendars Integrated Across Groups
Firstly, I am truly baffled by the fact that there is no share function on calendars, but I have seen the comments from Zoho personnel so I know it is soon coming. That being said, Groups generally need to be streamlined and integrated into the personal desktop, calendar, tasklists.
I very much enjoy that in my own calendar, a task can be created for an event. This is an issue I have had with Gcalendar for some time. Still, there are no shared calendars or tasks. Worse, there are no group calendars (easily created with a share function). However, groups don't have calendars and the tasks don't sync with anything. If I am a member of a group and a task is set up in the group page, at the very least, this task should sync with the task lists of all the members of that group, and ideally should sync with the groups shared calendar.
This makes the report function actually a very useful tool. As of right now, I would have make reports for my personal tasks lists and then for each group of which I am a member; or I spend an a half hour consolidating the lists. Calendar's have to be manually synced with tasks, and there is no guarantee of consistency of task and calendars across the members of a group.
The bottom line is that without these types of functions, groups are worthless for well syncronized operations.
