Something else that came to mind while reading some other topics here on the forums: being able to choose our starting equipment? Creating our character the way we want is kind of a big part of D&D, and this does include what equipment we start with. The classes get options for their starting gear in the PHB and such for a reason, because maybe you like to play a cleric with a mace and a shield but I want a warhammer on mine instead (just an example, don't even remember if warhammer is one of the proper starting equipment options for the cleric).

And stealth. Please, for the love of god, make it so when I make one of my characters go into stealth they all go into stealth as well. I am so tired of having to click through each of the 4 characters to tell each one to individually be stealthy. If my PC in front starts being stealthy, then having shadowheart and gale behind me just continuing along like a couple of bumbling idiots until I force them into stealth as well is not helpful. Also, make it so ungrouping party members is easier. The whole "drag to unchain" thing is annoying. A simple button to press that selects the entire party, or select them by individual portraits to only control that one character and have the others stay put is much simpler to use.
