Hi c-m:
sorry, the demo-link is broken. I haven’t it anymore online.
xett is something like a framework, with which you can create projects and different tasks for each project. You have all project/task files (getdatas.php and template-files) in a folder of your filesystem. The events or bookings or what else can be documents or datas in custom-tables.
these are examples which are done with xett.

Listing and editing can be done directly from links out of the calendar.
The next generation of xett is named ’blox’, which is basically the same, but can work together with Xedit for ajax-based frontend-editing and all used template files can also be modx-chunks.
example with blox is here:

If you are interested on Testing it, how it works I can pm you an login to my Xedit-Testpage
