As someone whos written HTML, its really just a CSS file with a call to a button. this would take a single person a couple hours max, a team of 3 could have it done in 30-45 mins. we honestly dont care about it coming with the new, just give us the quick and dirty dark mode and fix it to work with the new stuff as it progresses. you have a YEARS worth of people SCREAMING for dark mode and you consistantly dismiss it by saying "its coming with the new features!!!". if for whatever reason its that hard for you, i can have it done probably by the end of the week (i work full time and im not going to dedicate all my free time to provide you with a solution for free. pay me and itll be done within 2 days).
