Some ideas are nice but others I don't agree about.

- Less junk items -> This is not a batman game here in which you get only useful things. Divinity is an old school RPG and junks are as much important as useful items.

- A way to automatically distribute potions among the team -> again, no. The management of your team is one of the important parts of the game. So why would you have it done for you?

- Automatically pick the most qualified character -> No obviously. It's your role, as the player, to pick up the right character. We are not children so we don't need to be guided in our choices.

- Merchants should always have gold to buy your items -> completely irrelevant to a real sense of economy. So I am completely against this one too.

The others are good ideas I think.
