dark mode = good idea. not inverting the color hues = bad idea. need to hue rotate 180 degrees after inverting to get the colors to go back to their original hue. kinda obvious. not even remotely worth $25, though. maybe have a lite version for new programmers? it’s just “nice to have” to be able to look up things with your app, vs online (which, i am online 99.9% of the time). oh, and the “R” icon is lame… why not use the offical “R”? you can even grab the icon out of the app package. not hard… developer needs to hire a real graphic designer.
