The opening name that hides on you!

@Toadofsky
By 'at all times' you mean on the analysis board or while playing. If so I like the idea. The best way to learn and remember things is to see the information WHILE it is important. Then it really sticks into your brain. Lichess used to do this for a very short time.

I mean, that's my own opinion but theoretically it could be contentious since players benefit from seeing when they're "in book". Sigh.

Any such benefit doesn't seem to be that much to me becuase for one thing it doesn't really tell you when you're not in book anymore. Even if you play a really really bad move, the name of the opening remains unchanged. And a huge percentage of the time if you make a good move the opening name doesn't change either.
Any drawback along those lines is trivial IMHO and the value for people to become literate to opening nomenclature is very significant.
