I've often had a similar desire. I see the suggestions here for books and courses, which I don't dispute as good sources. However, I've come across good designers who have not gone through such extensive training. They haven't taken a 3 week course on typography and font selection. Yet their designs look and feel amazing. Do some people just have a natural knack for design while us hackers are forced to go through extensive courses to just get the basics? I'm personally interested in just a simple list or article on the basics of modern and aesthetically pleasing design. Something like, "rounded corners are easy on the eyes, use them here, but not here." "Button shadows work in a case like this, but not this." "Your background and foreground colors need to complement each other, here's some pairs to try." I have however never ran across such a list/article.
