The KiCAD main window has changed. It looks much better, but we really need to get back the display of the full path to the project somewhere. I have two parallell project folders for the 5.99 version and the 5.1.x version, and when opening a project in either of them I cannot risk that they get mixed up.
I really do not think there are much issues with the new icons in the main window. Effort is better spent evaluating the many icons with inappropriate red warning marks that are also often hard to distinguish at small sizes in the schematic editor.
