I love Sense, it is one of the main things that made me want the Eris in the first place. That said, there are a few things I would change/add to that I think would improve it.
- The ability to uninstall ANYTHING that is on the phone.
- I would like to see HTC open up their apps/widgets so that you can link an another app to a widget. Example: Using the clock/weather widget with a different weather source or using the peep widget with another twitter app.
- Being able to use a home replacement app as one of the scenes. So you could be using dxtop with one theme as a scene and using original Sense as another.
- Make the number of home screens user selectable. 1 or 2 for some and 20 for others if they want it.
- Ability to change the color of ANYTHING on the screen. Want the notification bar to be green and the buttons at the bottom to be orange, done.
- Ability to change the bottom bar buttons to open any program you chose.
- Custom LED color options
- Custom trackball color options
- Voice dial via bluetooth
