I see nothing wrong with the current main menu, but it is a bit over complicated and is rather clumped together.
After you first load in after tapping the screen, you should have the following options:
Single Player
Multiplayer
Missions
Public Missions
Mission Editor
Options
But in a horizontal line, or three on top, three on the bottom
Single player would be the following:
Dogfight
1v1 or 2v2 as options after clicking Dogfight
BVR
Close Air Support
Strategic Bomber
Loadout Viewer
Tutorial
Fun Modes
Time Trial
SAM Survival
UFO Attack
3rd Person
Ship Attack
Bomber Escort
