I haven't been playing this game long but I've had a few nags with it that don't make the game unplayable it would be more enjoyable if they were changed. One is picking your skills to use as actions. You have to click on the action button then select the skill then use the skill. So now if I have a locked barrel ahead of me I have to go through the skill list pick lockpick then unlock the barrel then make sure to change my secondary action back to my spell so I don't try to unlock the next monster I come upon. I usually have 3 or 4 skills that I use commonly, pickpocket, lockpick, and a spell or two. So having to go through that everytime for each use of each skill becomes tedious. I don't know what buttons you could use for the quick assignment for the skills as the function keys and a few of the numerical keys are taken. Maybe ctrl+numerical keys?
The second thing was specifically for the lockpicking and pickpocketing skill. Can you make it that the member using the skill has to go up to the target to perform the skill? It's not gamebreaking, but for lockpicking I keep trying to do it from across the room, and for pickpocketing it just makes more sense to me that way.
Oh and I don't like it if you give something to the other members they equip it immediately if they can. Usually I shift around equipment alot because of weight issues, not because I want another member to wear or wield it.
