         - Multiple monitor support (currently only main display)
         - Accelerated blitting support
         - Set the window icon (dock icon when API is available)
-        - Avoid erasing window on minimize, or disable minimize
+        - Fix white OpenGL window on minimize
+        - Find out what events should be sent/ignored if window is mimimized
+        - Find a better way to deal with resolution/depth switch while app is running
+        - Resizeable windows
+        - Check accuracy of QZ_SetGamma()
     Problems:
         - OGL not working in full screen with software renderer
         - SetColors sets palette correctly but clears framebuffer
         - Crash in CG after several mode switches
-        - Retained windows don't draw their title bar quite right (OS Bug)
-        - Should I do depth switching for windowed modes? - No, not usually.
-        - Launch times are slow, maybe prebinding will help
-        - Direct framebuffer access has some artifacts, maybe a driver issue
-        - Cursor in 8 bit modes is screwy
+        - Retained windows don't draw their title bar quite right (OS Bug) (not using retained windows)
+        - Cursor in 8 bit modes is screwy (might just be Radeon PCI bug)
+        - Warping cursor delays mouse events for a fraction of a second,
+          there is a hack around this that helps a bit
