Please fix:


* Messages, messages is a mess
* Slow shutdown times
* Laggy mouse behavior when taking a screenshot
* Bad drivers when running dual monitor setup
* Invisible cursor when coming from a fullscreen application
* Random re-indexing of Spotlight
* Time Machine backup disks change name to random names
* Slow animations when used for the first time in a while
* Load times of Safari is sometimes long for no good reason
* Make the stacks in the Dock better, when watching a downloading file you can't open it when having the stack open. Make it live.
* Add a simple 'location' option in Calendar that let's you pick a contact from the Contacts app.
* App Store is slow.


Thanks.

Let's hope this is the update which fixes all of the visual flaws. (leather flap covering part of the notes list, reminders being the only app not going full screen, the peculiar choices full screen switching makes with itunes and others, etc., etc., etc.)

oh, and I hope it fixes the sporadically missing mouse cursor problem.

Hey Apple, how about fixing the full screen problem where if you have more than one monitor and you go full screen in an app, you can no longer use all the other screens because your $#!t ass OS thinks everybody uses one monitor.

To paraphrase a Futurama meme:
Your software is bad.

And you should feel bad!
