Do any of these apps exist?

If not, I hope someone with programming ability (cough, probably some of you here ) can make some!

1. Any competent music app. The default one is pretty worthless, and the "best" (I use that term loosely) 3rd party one I could find was probably MixZing, but it leaves a lot to be desired

2. Any competent camera app.. The interface on the default one pretty much sucks, and doesn't focus very well even with the green corners. If you look at Google Goggles, it has a VERY nice-looking full-screen camera that takes better photos than the default, but it can't be used as an actual camera, only for searching Google...

3. Built into Android there is the "quick launch" feature to launch apps by pushing a combination of keys on the keyboard. Is there an app that will do the equivalent of/something similar to this but with the soft keys under the touch screen? Or instead of a combination, something like holding down the menu button will bring up an app (such as how holding down the search button brings up Google Voice search)

4. A "tweak" that allows the camera button to be pushed when the phone is in sleep mode to awaken it to the DEFAULT lock screen?

5. A "full version" of Caller ID Faker?

6. Better music widgets?

Any other really good apps I might not have heard of?

Thanks
