It appears the dark mode feature is completely gone now, which is very frustrating. I see no "Themes" option under labs as described above.

This thin font is so hard to read, and increasing magnification in the browser creates different complications. PLEASE consider changing the font colors, or bring back dark mode. Why does it need to be green?? Coupled with this thin, barely there font, it gives me a headache every time I log in, and I can't afford to put off my accounting but can't stand looking at the screen.
