It is good service, do you have plan adds altcoins price chat in the future? I think it will make more famous and there are many people who use your services, because there are many choice on this service.
It's possible but definitely not coming in the near future.
If you're interested in help with setting up an altcoin chart or two, let me know. Full time web dev here and I've made similar image tools (linked in my sig). No charge.
