Thanks for the Tokyo Night recommendation! It looks much better than the default themes or the ever popular material themes. One question about the font size, what resolution monitor do you typically use? Font size 12 seems so small to me!
I'm glad I could help. I have a Macbook Pro with a 2560x1600 Retina Display and usually another monitor with 2560 x 1080. The retina display is 13.3 inch and the external monitor is 28.5 inches.
