Yesss, I found it under Start >> Settings >> More >>
Start Menu Layout Switch
Many thanks Bawaji
Regarding Arabic Lang, I found the files for HTC HD2 and it worked good on my Imagio (with a little untranslated words) .. here are the files from
ce4arab.com .. you can add Arabic as an input language or fully Arabize the interface.
For info: I wanted to change from Sense only because of the small size of Start Menu items.
