Gauss said: +1, Although I would expand it to be more than just themes. Fonts, font size, color, background color, and icon size....give control of these 5 things and most accessibility and preference issues become resolved. Between color and background color your contrast issues are resolved. Between fonts and font sizes and color control as above your readability issues are resolved. Icon size is just basic, many folks need larger than tiny icons for a variety of reasons. These are not just preference issues, they are also accessibility issues. One size does not fit all. High contrast solves some accessibility issues while low contrast solves others. Being able to change color settings helps for different types of accessibility issues, in addition to preference issues. Different fonts and font sizes help a variety of folks. Some fonts are more difficult to read with some eye conditions, others are more difficult to read for other conditions and of course, preference. One size does not fit all. This is really about inclusion, not just preference. I'm glad that someone else has finally addressed the accessibility issue. This is an absolute ADA nightmare. Like best practice dictates, you should always run your page through an ADA checker. If you run any page of Roll20 through a checker right now you'll get more than just a mountain of contrast issues. They also do not include alt-text for pictures or most links.
