I'd love to be able to create new sheets by right-clicking on the Main/Sub Folder header and have the new sheet automatically file into that project browser organization. Scrolling up to the top to expand two + marks and populate the organization parameters is a bumpy workflow that is whole unnecessary. If Revit could default the sheet number to the next in the series of the folder organization (rather the sequential next number after whatever was lasted edited), that would be awesome.
There is also no reason this couldn't be applied to views as well. Right-click > New View > select view type from pop out secondary menu. I realize this would only be possible for floor plans, area plans, and drafting views, but I think it would help some of my weaker Revit users work in a more natural flow.
