Inspired by the nice Firefox Extension I had to make one for Opera as well..
They will install automatically when you click them and look exactly like the Firefox extension. (If you dont trust them, right-click and download to have a look before placing them in your profiles menu folder). Both menus will work in any Opera version after 7.11, but they include menu changes that are specific to 7 vs 8.
I will post updates as the new Opera versions come.
- For 7.54
(PS: No need to restart)
