One thing I would like (maybe someone else mentioned it) would be to have a 'wilds' style encounter setup option, so I could create a game with GG0/1 strats and schemes, or an option to at least show all the strats/schemes for updates / adds. Aka, I've wanted to play GG1 schemes with GG0 strats lately, but there's no easy way to do that.
Additionally, it's not super clear to know how to generate non gg1 games (as it looks like you need to save before the regenerate button).
