Just a thought here, I wouldn’t know how difficult this would be to implement:
I think it would be helpful if villagers were sorted by their stats for promotion. In other words, if you click on the wooden sword and open the dropdown box to select a villager to promote, the ones with the highest HP or other relevant stats would show up top, and the less “fit” villagers are lower down on the list.
Again, I don’t know if this is feasible, but it would be nice to have an easier way to get the most out of your villagers abilities (e.g. rankings or a menu of some sort with stats on it)
BTW: I’m LOVING the performance boosts in the newer versions! I’m able to build a lot more in the hour or so of free time I have each week 
Keep up the good work!
