re: What iPad 3 Really Needs: Revised OS
Agree, 100%! Several things come to mind immediately...
Absolutely the top priority would be a customizable status bar with a hide-show option. Apps are able to hide/show the bar; there should be a system wide option. Putting different things in there, or changing what's there, would be good, too. Personally, being hit over the head with the time in the status bar is annoying.
System wide color themes... e.g., a night mode that would put pastel-colored text against a black background, for night situations (aka astronomy, medical night rounds, airplanes, evening and nighttime reading, bedtime to not disturb partner, etc.)
Customizable keyboard, and even expanded arrangements if desired.
Flexibility in home screen arrangement... especially tabs and tabbed home pages! It'd be good to have something akin to Z Launcher on the Palm OS. One would also want to see a sliding dock toolbar to include more apps.
Download organizer that would permit several designated apps to update their content in the background (e.g., various news apps, tech apps, weather, satellite observations, exoplanet databases, NASA Sun apps, etc.). It's silly, and a nuisance, having to go to each manually.
The date/time picker looks positively archaic; 19th century even. For a modern, cool, 21st century device, that is aesthetically ridiculous--and something I'm forever surprised got past Steve Jobs.
Updated, more fully-functional PIM apps-- todo, calendar, etc. More than a decade ago, Palm had this down pat; Apple is still playing catch up.
Yes, both functionally and aesthetically, the iOS needs an overhaul. You know, something that you just "have to see. And touch!" :-) Wednesday, Yerba Buena, anyone?
