Add an option to display the previous UI and fonts or change fonts and colors

The new UI design and fonts are harder to read, especially in darkmode. The font is too thick and the previous design was easier on the eyes. In darkmode, the bright white thick text is not easy to look at. The old design was overall more coherent and nicer looking, I don't understand why it had to change, but if a toggle for the old style isn't possible, perhaps changing the fonts and text colors could be possible? Using the app with the new design makes it harder and less enjoyable to use for me.
