Interface
2c. That's utterly ridiculous. I don't want my game cycling my hard drive every 5 seconds, causing slowdowns. This game already has autosaves before most-all combat encounters. It's up to players to save regularly. If they're too dumb to forget to save, that's their own problem.
Not 5 seconds. 5 minutes. The autosaves are few and only before major encounters (most combat encounters do not have autosaves). Also, it would be optional, so if you don't like it, you don't have to enable it.
Gameplay
7a. I don't see any alternative to stack splitting which wouldn't be more annoying. Most of the time you want a stack to go in all at once then place another stack on the other thing so you can make them in bulk. Just get over it and accept that sometimes you have to split stacks of the same item.
The alternative would be placing one stack in one slot, then placing the same stack in the other slot. When you place a stack in a crafting slot, the stack does not disappear from your inventory (as in moving from bag to the crafting slot). It's still there. You can even drag it to the other crafting slot, it just currently won't let you actually put it there.
