I am happy to see that Revit finally integrated windows layout abilities (2019), allowing for moving tabs around easily. The one problem is that I can no longer use Palladio X BIM Layout, which increased my productivity by letting me set my preferences for size of the main window, and bouncing the view I wanted to work on into the largest open window (while keeping the layout intact).
My suggestion to the Revit Development team is to create a save windows layout (similar to what exists in many of the Autodesk products & in almost all other 3d modelling software) so that way I can use the layout that works best for me without having to drag windows around every single time I want to adjust. The window layout would remain the same, and a button to move the current view into the largest window (left or right) would exist to be able to switch easily between major views. For anyone confused by this, see what Palladio X BIM Layout does in previous versions of Revit.
