How to change G-Code Flavor - and why?

[FalmouthLouis 3]

Using Cura 3.4.1 I seem to have lost the ability to show quite a number of items in preferencies. Specifically, I want to be more precise on Retraction distances but, in the information in Configure/Preferences I am told that it can't be shown because of the vlues in my G-Code Flavor. I am asked to change values in this flavour, but I can't find any sign of where I do this.

 

The reason I'm asking is that I seem to be stuck with a Retraction default of 4.5 mm on my UM2 which seems to be producing some unwanted stringing. I want to experiment with some different retraction differences.

in Cura: "Settings -> Printer -> Manage Printers... -> Machine Settings"

In this case you can use the default gcode flavor ("Ultimaker") and "TUNE" the retraction settings (distance and speed) directly on the printer (during printing). Wouldn't this be much easier, as you want to experiment anyway?
