One of my absolute favorite Revit tools is the Selection box tool. Select multiple items in Revit, type BX and it opens your default 3d view cropped down to your selection.
The feature request I would submit is the ability to do this same process on any already created view. Even better would be to make it a right click feature in the project browser.
Currently the only way I know to do this. Make a new 3d view, right click on view cube and orient to view. While this process works, it has its issues. For one, if you have a project with a large amount of views it take time scrolling through a long list of views to select. If you need to make a 3d view per level it will take long time.
Right click on the view and create 3d view would significantly decrease the time.
