I'm using RadScheduler with TimelineView, i have ExactTimeRendering and it shows the appointments clear.
Since i have the slots with 12hours, i want to adjust an extra hour, but when i resize it always adjust an extra 12hours. 
 
Would be very helpfull to had a property to allow exactappointment drag, so i can resize 1 extra hour instead of 12. Something similar like in radgrid, when resize columns it shows me how much pixels, in this case i want it to show the time.

Currently the RadScheduler is capable of binding to a web service, as described at http://docs.telerik.com/devtools/aspnet-ajax/controls/scheduler/web-service-binding/overview. This functionality requires the creation of a web service and custom provider classes.

Please create an option to bind directly to the Sharepoint Lists.asmx web service with client side mark-up identifying the calender and the view to be displayed.

This will require authenticaiton either by pass-through, anonymous user account, or a specified service account.

The managed API has been out for a couple years now and is accepted as the way to use EWS vs the proxy class now.

I would like to strongly suggest you considering some sort of workflow capability available. My application provides solutions where tasks (Individual and concurrent) are spawned and we have to track the requests, users, and integration with underlying applications. This is all done manually or custom coded. 

If there was a way to have out of the box workflow capability, that would make the life so much easier. Having drag and drop features to create workflow diagram, use the rad screens to create forms, and integrate with underlying applications.

Please let me know if a workflow engine is in the roadmap ?
