Thanks a lot to Side-7 [link]
for giving me the permission to port his awesome Red Ribbon [link]
to GnoMenu. All the credits goes to him!
By the way, this only works for top panels! And works better with 24 pixel panel size
1. Extract the .tar.gz file from the .zip file.
2. Right-clic on the GnoMenu icon and go to Properties.
3. On the Start Button section, clic on Install and select the .tar.gz. If it asks you to type your password, then do it!
4. Select Red Ribbon from the Start Button combo file.
5. Enjoy it!
