Other application UI
* Draw over other apps
System tools
* Read battery statistics
* Read Home settings and shortcuts
Your applications information
* Retrieve running apps
* Reorder running apps, run at startup
Phone calls
* Directly call phone numbers
The ability to arbitrarily run at startup, read what apps I'm currently running, and draw on top of them all concern me, and I've chosen not to accept the update at this time as a result.
