Can these usability problems be solved with 3rd party apps or hacks?

Does anyone know of any fixes for the following?

1. When the phone's screen goes black for power savings, all the buttons also stop responding. Can the phone be set to "wake up" upon a hardware button press, and also execute that button press (end call, launch messaging, start button, etc.)? This is especially frustrating when trying to hang up a call and the red phone button won't work because the screen is off.

2. The "speaker" icon that allows you to control the phone's volume settings is WAY too small and too close to other tappable icons. This makes it very dificult to access volume settings without the stylus when not on a phone call if you are moving or driving. The jog wheel controls in-call volume which is nice, but is there a way to have a larger volume setting icon or map the jog wheel to volume settings or something that requires less precision when NOT on a phone call?

3. The "X" that you tap to close/minimize a window is also too small to tap without a stylus if you are moving or driving. Is there a way to make it bigger or some other shortcut way to close windows that doesn't take as much precision?

4. The number buttons on the phone dialer screen are too small to accurately tap with a finger while driving, and the keypad disappears once connected. Is there a hack or alternate dialer that has larger numbers and leaves the keypad on the screen durring a phone call? The on screen Talk and End buttons could easily be ditched to make more room since we already have these hardware keys on the front of the phone.
