The addition of the altitude indicator into the UI was and still is a nice edition; however some of the UI elements above the AI are of long overdue for a refurbishment. Over the past few months, I've seen a few suggestions regarding the customisation of what menus to display on screen and I have a fresh proposal that can be the best of both worlds.
Combining the speed, altitude, vertical speed indicator menus to the AI to create a semi-primary flight display. This would help declutter the screen for more visibility. This would also make everything more compact and convenient so persons wouldn't have to make the hassle to locate the AI and the menus listed. Due to these elements being combined, the fuel and throttle menus can be reduced in size as shown in the image.
One drawback to this would be the new size of the PFD being a bit wide, but the benefits would outweigh them.
Hopefully this feature would be added to the main game and would be a part of the continuing act of refurbishing the UI.
