Spending more time thinking about it:
- Agreed with the bugs issue, small things like Window-server still being a RAM-hog, generally bumpiness etc.
- slight tweaks to the UI, can't believe after all these years dragging a drive to the trash-can still says 'Trash' instead of 'Eject'.
- Better third-party mouse support, certain apps like iTunes have become horrendous with an external mouse. Calendar completely negates the ability to scroll using a mouse.
- Independent scrolling-directions for different peripherals, scrolling in a mouse is different to scrolling on a trackpad, don't make them the same. Give us control!
- Window-snapping like Windows, a small option that's phenomenally helpful. I appreciate they want to push full-screen apps more but giving the option would be nice.
