If we are stuck with the skin, at least do some polishing to it please:

  • fix the artifacts on the edge rounding (use better antialiasing and larger alphablended shadow)
  • merge minimize/maximize/close in one block and get rid of the double border around them
  • don’t use rounded edges for the content area and sidebar buttons
  • get rid of the doubled top/bottom separators, scroll submenus, not the whole sidebar
  • align top sidebar button with content area
  • make sidebar sub-menus look like they slide out of the parent button (no rounded edges and continuous gradient from the parent button to the submenu)
  • fix maximized state, so that the borders don’t go off screen (especially on top, where 1/3 of the min/max/close buttons are hidden) and don’t use rounded edges
