Voted yes for convenience's sake.

I wholeheartedly agree with this.

Something like Cryengine 3's sdk or even Far Cry's editor.

Enemy movement should have it's own tab and have easier/more functionality.

Should be able to easily create a new map from nothing and texture it using the ingame textures and custom textures.

Should have to be both 2d/3d with a toggle in between the two.

Keyboard to command to enter/exit the player. (ctrl+g and esc on Cryengine 3)

Awesome, love that there is an actual response!

Been playing around with it more and noticed that sometimes it will work and immediately stop working. Also, turn left/right will also bank instead of turn.
This is getting annoying now.

Even changing the user file with all the keybindings and still no luck.
It always goes back to banking instead of yawing.
