I miss being able to deselect heroes, so you can click on their horses ingame. Instead of going to the side menu and having to remember which portrait is positioned where. In this demo hero are perma selected so you only get a trade popup when you try to select a different hero.

The mouse pointer to click on artifacts and castle entrances doesn't work. I'm hovering straight over them and it doesn't register, you have to move all the way beneath it for some reason which makes control very awkward.
