I use a lot of calendars. In my mind I have them grouped as "family," "health/personal," and "work." They all have several calendars and task lists associated with each, and not all of them are mine to merge or otherwise manipulate. It would be great to have schemes of c&t lists to select.

I did notice on using a different app that if I select calendars to be viewed there, they are also selected, then, in Business Calendar, but without stars. That means if I do this, I have to go back and "re-star" my calendars to get my favs list (tabs) back. This isn't a whole lot of fun. I know this is a system setting, then. So, basically (from my simple place I'm thinking) the code would have to go back and reset the selection.

I also have an app that used the indices (Add Your Template) and it frequently loses the reference. Tasker uses calendar names, and it is so much more reliable (and then if I change the name of a calendar, it's something I should expect to break.)

I also noticed there was a similar idea here, but it wasn't very explicit, and it didn't seem quite the same. I think this would serve that need as well.
