Feature request: public comments on moves in opening explorer

It would be cool to have a button in the opening explorer where you can see a comment thread made by other lichess users. Each comment thread would be specific to a position in the opening explorer. Then, say someone enters a few moves into the opening explorer, and they have a question about that position, or simply want to talk to other people about that position, they can start posting/engaging with comments for that position.

I think this is a good idea.
Additionally, I would ask for an option to switch between public and private comments. Private comments can be very useful during opening preparation, They can quickly remind about good or bad moves, plans etc.
