Something really should be done to improve this part of the game, but I am doubtful it will happen. DOS2 had the same system and also has consistently had calls to change the system. What I am finding is that it is worse in BG3 at the moment because character selection does not always 'take' with the first click, and even if it does, attempts to drag and unchain the character aren't always successful, resulting in the character running to the spot where I meant to move the picture.
