@ john.baskerville: Hi John,
If I understood you right, you want years expanded by default, and the months are collapsed nesting the items. if this is right, then this will require rebuilding the code which we can do in a future release, but right now this is not possible in the current code.
I have another module that displays only months, no years but is does not have the JavaScript this module uses.
The good news we are making a complete Zoo App that has a unique feature in it to shows the time line in it, that might be of interest to you, it won't be out before 1-2 months as we still needs to iron some functionality in it.
I will post an update here soon when we have a beta.
Overall, I will talk to the guys and see if they can put your request on the task-list.
Thank you for the positive feedback.
