When working on a project with many views, especially 3D views, it can take a while to locate the one view we want to work on or see in detail. Naming conventions go a long way to alleviate this issue but are not enough.
I propose that Revit could generate thumbnail previews for each view and show these as a tooltip when hovering the mouse pointer over view items in the Project Browser (see attached mock up).
This feature would be fairly straight forward to implement. Revit needs to take a snapshot of the current view when the view is being closed or dismissed in some other way, such as switching to a different view. That snapshot then becomes the thumbnail preview for that view. The thumbnails don't need to be large but a range of sizes should be offered as a customisation option (small, medium, large). These could be displayed on mouse-over as a tooltip or in line next to the view item in the Project Browser (similarly to how image editing apps show thumbnails of layers).
