UI: Please add separate font sizes for UI and code

[dalbocha]

At the moment I found only one place to change font size of UI and code: in Preference-Appearance. Increasing/decreasing the "Default Font Size" the font size for UI AND code changes both.
It would be nice to set the font sizes for ui and code separately.

Done. You can download the latest CI build from Github Action.
