I've done about a dozen games (a combination of GR and DM) now and cant say I have ever bought an item from a shop to use (though have to open up a podium). While I happily get to level 10+ in most cases still. So I tend to be less than worried about scrounging for shop items at the low end of the game. Though I would like to see the tabs idea (or craftables storage bags). As to the Skyrim comment, its likely a bit unfair on the whole as Skyrim has a horrible inventory management interface. A good interface makes a huge difference.
