I'm surprised you haven't seen this screen set because it's been part of the development version for a long time now. I'm like you, I hate the look of this new screen but it's easy enough to change the screen set and revert back to the old style. My Son uses the new one and I use the Old one but both are using V1.2113.

The main change I've noticed is that it now allows you to set debounce for inputs, Homes, and probes separately when before it just did a blanket debounce on all the general inputs.
If you load the default screen set rather than the default 2019 screen you will see in the general settings some new fields(2654 and 2655) for probe debounce, these are new fields that were previously reserved in the fields by number docs.

I've also noticed it's much faster and smoother updating the screens/toolpaths so maybe they have tweaked the base code etc.?
