Retraction, and Z offset

[MTUpower]

Hi Mr Jyers, firstly I want to thank you for this firmware, utterly brilliant and has transformed my Ender 3 V2. There is one point that I noticed. Before I had your firmware, if I had the Printer connected to Pronterface and was adjusting Z offset using same, you would see the Z height reading change on the screen now it does not? As a question, is it possible to have a screen where you can adjust retraction length and speed? on the fly as it were in the "Tune" menu?

Kind Regards
