Invert Alt-Middle Mouse navigation?

Thanks alot for Y, but Invert X is still missing. maybe there’s a stand alone program that inverts mouseX than alt+LMB pressed?

I can live with scaling than scroll used is independent from distance from object, though it’s a bit annoying
I also can live with rotation being independent from where mouse points when alt+LMB though pressing “F” each time is really time consuming, But Inability to inverse X is just AWWW

I hope that one day all 3D apps will have standartized navigation like in Cinema4D) This is really a very basic and crutial feature…
