A minimal and flat theme for the website https://youtube-playlist-randomizer.bitbucket.io.
I find the ytplr website really useful. But the ui of the website is really not that great. So I tried to update the ui a little bit to make it way better than before.
This extension is available in mozzila addons for firefox: https://addons.mozilla.org/en-US/firefox/addon/ytplr-minimal-theme/
