Yes, I'm still using my robust old netbook with a 600x1024 pixel screen with Qt Creator. This worked more or less well until Qt Creator 4.3.0 which became too high for a screen like this. Using Gammaray I've found out that Welcome::Internal::Sidebar determines the minimum height of the whole application. When hiding this widget, Qt Creator scales down very nicely to 400 pixel height. Maybe this widget could also get scrollbars like the QStackedWidget (where one can open or create projects) right next to it when the main window gets too small?
