This might not have been a feature to the game, but I really preferred when you could pause the game, and select the parts you want, without having to load for 5 seconds each time, and instead loading for 5 seconds just once. I think it was a really nice time saver but the latest update has changed it, I suppose. I don't know if this is just useless to ask for, but the pause button allowing you to select multiple parts without the game loading for 5 seconds for each part was just really nice in my opinion.
