@Keepskite you have to have a space between the .exe and the rest of the command (.exe --show)

@AltairAssassins Go to the shortcut properties, in the target field go to the end of the file name. At the end of the .exe add a space and then the rest of the command as seen above. (.exe --show) then close and restart Opera, go to extensions and find it there. You will also see a ton of others that you didn't know where there.

@merijn2 Leave a space between the .exe and the command (.exe --show)
