Volume2 was renamed to Volume² - advanced Windows volume control. I was made many improvements. Firstly it is interface  and logo of program.
Main changes:
- set default device from Volume²
- change volume active application
- show OSD, when changed volume in system
- set on hotkeys combination keyboard key + mouse key
- safely remove USB flash drive
- show current battery life percent
