Add an option to create games from position

It would be great for practicing openings

And sorry for bad english, if it will be visible

if you open tools > analysis board (or board editor). you can create a position - and create a game from that position by clicking continue from here (or hamburger menu > continue from here).

If you mean challenge someone, you can already do this: Play with a friend --> Variant: From position.

Thank you, but it's a link, how can I do an open game from position?

You can't. This option is only available as part of a "Play with a friend" feature.
