Changing the Soft button for Messaging and button for lock

[Kasracer]

I've been extremely happy with my Mogul so far but I have three things that bother me that I'm hoping someone knows how to customize them

• I changed the registry key so I could change the soft button on the today screen (bottom left) to open my messages but it's annoying how it opens on the list of accounts everytime. Is there a way for me to click on the soft button and take me directly to my text messages? Perhaps something I can pass to the pmail application?
• I'm really used to my Treo 700wx that had the bottom left soft button as "New" when you're inside of your messages. For some reason the Mogul has this button as delete so I've accidently deleted a few messages. Is there a way I can change this button from delete to new?
• And lastly! How can I use a hardware button to engage my phone's lock rather than tapping the screen each time? I would really like to be able to press and/or hold briefly the red phone button to do this but still have my hanging up ability. Ideas?

If anyone can solve these 3 things for me.... hmmbut I don't really have anything to give you but I would be very greatful!
