1) I think no autosave is better. Making such a feature in easy mode (explorer mode) why not but when you just have to press F5 for a quicksave, I prefer to chose when I can do it, autosave popping randomly (and after X Min that would mean even in combat) isn't a think I'd like.
2) True. The camera should be more zoom out like the first one. I don't like the new angle too, it was more "vertical" in the first one and we had better visibility
3) Already exists. You have gold, you can pay with gold, you can seld for gold (but vendors have a certain amount of gold, to make it more realistic). You can also use the scale button.
4) Didn't encounter the problem, I rarely buy things in more than just 2 or 3...
5) Already been said it will come, it's the alpha, give them some time, it wasn't the first thing to experiment, you can hardly mess up a game with just a "sort" button.
