To start with, this isn't really a technical suggestion, as it doesn't have to do with mechanics. But in the future I'd like to hear/see the companions actually liking/being friends with somebody in the party who isn't the player character. We do have some snark as they become familiar with one another, and that's fun, but over time I'd like lines of dialogue that suggest something a little deeper than the vague familiarity of acquaintances. Maybe we could even see some little interactions at camp - like Gale and Wyll discussing magic, etc. I just think it would add a lot in terms of character development.
