As strictly a "user", I can't agree with you more. I'd love for the UI to move away from the "phone interface" (all those pop ups and hidden menus) and move to accessible buttons/buttons with drop downs on menu toolbars for commonly used functions.

For example, an app switcher button with a drop down list of open apps on the home screen or a customizable toolbar in "docs to go" for instance for those everyday operations like selecting type, font attributes, copy/paste.

Get busy guys!
