A racial flip book would be seriously awesome, no argument there.  If we are making a wish list I’d also revamp the careers.  I don’t hate them but I’d much rather just have one large perk web where you can develop as your adventure takes you.  Basically similar to how fallout 4 handles it.  The career paths there do offer enough variation that you can largely pick one you like and adding on multi-careers really does give you a ton of variety but still I’d prefer one large mesh – where you are just your characters. 

The careers as they are seem like a very legacy (WFRP/40k rpg writers got their mitts involved) thing. They seem like something more developed for NPC generation and less for players.  I think the only value they add is for players to tell GM’s the type of things they want to see.  If you have a player make a tech, make sure you give them ways for tech to solve the problem and not just the dump character for downtime.
