I love tixati, and I love that I can pretty much change everything, but I often use already premade themes and styles for the colours. Having to input RGB variables is much slower that just posting a hex colour code (like #0a0a0a, instant and fast). Sure I can convert the hex to rbg and then change r, g, b each for each colour, but it's extremely slow. Not sure how difficult it would be, but I think it would do a lot of good. Most modern applications that support theming support hex codes.

Thanks for reading!
