Font is small and blurry even at larger UI scale

I'm using a 4k display, and even with the UI scale set to max (Settings -> Experimental -> UI Scaling -> Larger) the font is small and blurry:

(not sure how to best convey the blurriness in a screenshot)

version: 0.13.1 (flatpak)
system: Ubuntu 24.04.1

After a bit of research, looks like you can scale with a Fyne environment variable:

FYNE_SCALE=1.5 flatpak run io.github.dweymouth.supersonic

Possible to make this scale configurable from within the app?

The "UI scaling" setting in the dialog is actually setting the FYNE_SCALE environment variable for the app. I can add a "Huge" setting to the dialog, or I could change how it's stored in the config file to store the FYNE_SCALE value directly, instead of the small-medium-large stting, so it could be configured by advanced users in the config file. What do you think?

Storing the numeric scale value in the config makes sense.

Most OS display setting screens allow directly specifying a numeric scaling factor. Why not expose the setting in the UI, rather than only in a config file? I suspect many users will need to tweak it since there are so many display variations nowadays.

To start it could just be a numeric input text box. If you want to get fancy (and assuming Fyne has the needed widget), a discrete slider could be added that increments the text box by say 0.25. The slider could replace the current qualitative size labels, while still allowing the user to set an arbitrary value in the text box if they like. (Could add qualitative labels to the increments, but I think the raw numeric value in the text box is enough.)

I can try my hand at adding a numeric input text box if that sounds reasonable.

I had avoided adding a direct numeric text box to keep the user from entering a value too large or small and ending up with a non-functional window. But I suppose adding a numeric text field and just bounding the numeric value to say 50%-200% would be good enough.
