- Allow more customization when it comes to badges in the dock. Like for the mail app, it would be handy if there's a badge for unread private emails and another badge for unread work emails.
- License some popular video codecs: from a Mac - the ultimate creative multimedia machine - I would've expected when I quicklook a avi file(divx, etc), that it would actually play it..
- Safari is still crap, oh and where is the option to re-open the last closed tab? Without having to go to history manually..Just steal some more Chrome features, just like you did with the search bar
- Mission control is more or less OK, except for the choppy animations once in a while. But pretty please, give us also some window management like Snap in windows 7.
- When I want to know the file size from multiple files, now I have to select them, right click, press option (so the "Get info" changes to "Show inspector") and then I can see the total file size for all these files. Works great, however if I forget to press the option key, and just press "Get info"..well..You'll have fun closing all 'Get info' screens one by one. Just fix this mess Apple and set the default behavior for multiple files to show the inspector and not an info screen for every file. Average Joe doesn't know the location of the option key, and it isn't intuitive anyway.
- Fix every bug in Finder, and allow more customization in Finder. Oh yeah, and view options for every folder gets confusing. And moving files (not copying) with a shortcut is also too cumbersome.
- Make it possible to move every window from an application to an external monitor without having to drag them manually one by one
- Make it possible to hide all other windows from an application except the one you're working on (example: 10 textedit windows, I just want to see the active without having to minimize the 9 others..)
- Fix airdrop, srsly..
- When cycling (cmd-tab), give us somehow a visible hint, that a certain app doesn't have any windows anymore..So I don't wait and then realize that there aren't any screens left. Or maybe just leave out the apps in the cmd-tab screen that don't have windows..Don't know if that's a good idea though, too lazy to think about
- Scrollbars look nice on iOS, but not so nice on OSX. Make them a bit more refined. And make it possible in settings to have scrollbar arrows.
