gnomenotification-areasystem-trayunity

the notification area in the bottom of screen is annoying, can i change the place and look of it to be as in unity? "at the right top and disappears when hover over it"?
and also is there an extension to change the icons of some programs from system tray to the upper panel?

Best Answer

shell extension Shell OSD can place notifications in the upper right hand corner.
