That is very a good idea! For now it is stateless & frontend-only. But I was thinking on improving it, like a prettier UI and adding a "print" button, or maybe a "export to png". If I ever add a server side to it, it will feature a share & see option.
Afterthought: actually, I was thinking on using IPFS to store stuff, but I do not know if its model applies to this scenario. Feedback is appreciated.
