I know the behaviour of windows as I used an Amiga for many years. However, after being used to er GUIs like X/GNOME, Windows, Mac OS I find it very frustrating that I can't
1. resize the window by just dragging the window borders
2. need to call "update" from the menu to relayout the icons in a (resized) window.
3. can't maximize/restore window size by double clicking the window title bar.
