Opera - turning off the annoying tray icon

Opera 9 by default starts up by placing an annoying, pretty much useless icon in your system tray. To stop it from doing this, add the option "-notrayicon" to the script starting it up. This file is usually found in

/usr/bin/opera

and change the last line of this file to

exec "${OPERA_BINARYDIR}opera" "$@" -notrayicon
