I don't know of anyone who has ever wanted to have the menu bar at any other place, except the top default position.
tray menu fails when user doesn't have tray icon enabled (like me)
Do you realize that this thread is 9 years old?
Either way, it still brings the same topic to the forefront. It's probably not any more likely to be amended now, unless you have any specific code examples highlighted to show how to call forth the menu bar with the Alt key, unless maybe it would be a better idea with a hidden menu to call it forth as a popup menu with all the main menu entries as submenus.And either way, it looks like development is not moving so swiftly, but I've been out of touch with the development discussion, so don't mind me.
