Despite it being a feature for a few years now, there's a tragic lack of sheets with Dark Mode available. According to the Community Wiki, a feature Itself with no Dark Mode (ouch), there's a total of 8 Sheets with actual Dark Mode Support, and another 4 which simply patched themselves enough to make them simply 'readable' with Dark Mode enabled. Considering that initial number is so low as to count on your fingers after three years since Dark Mode's implementation, I think it's about time there was a call for more support. Further, there's basically no real way other than trial and error to pick out which sheets have Dark Mode support. Why not put something alongside the other tag markers like Demiplane and the like to show which sheets have functioning Dark Mode? While many old sheets are abandonware, it might prompt some sheet devs that are still active to actually include it in their creations if they get a nice shiny badge for it.
