Just wanted to give you a heads-up that a minor tweak to the HeroMachine 3 Alpha has been uploaded (version A.22) that improves the performance of the scroll bars in the Load/Save window. You can now hold the arrows down and the list will scroll on its own, or you can drag the little handle in the middle for more rapid manual scrolling.
I thought I'd fixed the "sort by date" bug on that screen too, but it turns out it's still broken. Feh.
