Pop toast – I know it’s been overused by a number of different products, but it is still one of the most convenient and unobtrusive notification mechanisms available, especially if the mechanism is explicitly subscribed to and you have the ability to review the toasts that you may have missed or temporarily suppressed.
Drag-n-drop Plugins – I need to beef up on my AppDomain skillz so that I can support drag-n-drop plug-ins and additional functionality a la ASP.NET.
Consistent server-side error trapping mechanisms – All too often WebService and WCF service errors are either shown directly to the end user (bad, bad, bad), but since these aren’t trapped by Application_Error, they’re often not present in the server’s error logs. Need a better and more consistent way to handle these and get the error information to the developers and teams that can actually do something about them.
