It's mildly infuriating that the button doesn't say "Unstar" after you click it.

Question：I created a repository on my local pc, then I push it to remote github. I used a different pc, clone same content from remote reposity, then I created a NEW directory, do pushing, it didn’t work!! Any one ever got the same issue?

Git doesn't track directories, only files. If the new directory was empty, it doesn't exist as far as git's concerned. If you need a directory to exist, put a hidden file in it and add that to git, or have your build system create the directory when needed.
