Save Option in the Boards?

So, I came up with the idea for a save button to add to the League boards. I don't like publishing WIPs, but if I don't I tend to forget them and move on. But, what if we could save WIPs on the boards and access them later? It would be similar to Moba Fire, and I think it would help people be able to publish full pieces of work instead of of pieces at a time. What do you guys think?
