It was a closed beta (and almost remained a closed application).A strange stragey of releasing and publishing a tool program, not releasing it here as beta before, releasing it on herald as approved map tool, without a tilt map function!
But iam thankfull that there is somebody developing it. Thanks!
The Map Tilt was not added because it's not extraordinarily important in the grand scheme of things. It is useful, yes, but I'd rather have everything functional.
