Start generating next game before finishing the current one

[WiserOrb]

Some of the puzzles, like galaxies, take a long time to generate.

I would like a setting to allow pregeneration of the next game before finishing the current one, giving the user the ability to disable it if they choose.

Thanks for the amazing app, really enjoying it.

As I'm guilty of trying the limits of some generators such as Solo, I'd love to have this. This might be related with the feature request for the ability to have the generator run in the background while playing a game.
