eXtremal put a lot of work into a backend api that you can work with. You can certainly create whatever frontend you like. Just make http calls to the api he built, which is all over the instructions. However I like the minimal angular site he already made.
I have tweaked the backend and made my own api functions as well for www.zogpool.org and www.luckpool.org
I can’t really provide you with an answer to your question in a post. It’s just general web dev stuff anyway.
