Suggestion for the Extension
First of all, I'd like to tell you that you're creating great extensions. Your products have helped me a lot.
I have the suggestion for the extension (if you want suggestions :-).... I need to create the scheduling page for one of the sites I'm creating. The scenario is the following:
There are several levels of users (Admin with total control, Power Users with partial control, and users with limited control). Users have to have an opportunity to schedule event using the calendar (clicking on the calendar should allow users to see available time periods). Thus, users can schedule certain events while being able to see available times for scheduling. While Admin can control the time periods, list of events, and etc.
I've found several scripts for php that create the scheduling behaviors, however, they are extremely complicated to install and don't allow the customization for particular template and particular tasks that can be modified.
If such extension would be created I'll be more than happy to purchase it (and I'm sure, majority of your clients would like it too).
