As an Ottoman main, I would love to be able to select what unit will be produced from military schools as they’re being built. It’s so annoying to choose something and then cancel the default spearman.
Similarly, it would be nice to select toggles for other buildings that have toggles, for example:
Mali Mansa Quarry (Gold vs Stone production)
French secondary resource production from market
GUI-wise, if you don’t want the commands to overlap with the lone “cancel” command that you see when building a production, at least map it to the secondary Y-panel. I feel like this shouldn’t be hard to do!
