Maybe someone already mentioned this: it is difficult to remember the names of the villagers, because they sound the same, caused by the way the words are built (Lala, Momo, Tipa, Paipu, Pupa etc.): /consonant-vowel-(/)consonant//-open vowel.
If you change fi the number of syllables, the name gets more rythme and is more easy to remember.

I like the idea of keeping some animals, preferably animals you dont have to slaughter, fi chickens for eggs, cows and goats for milk and maybe some pets.

I also like the idea of having more communication and social interaction, like a few villagers going swimmer together or playing some game, children having contacts/activities with parents and brothers and sisters.

As already mentioned by others, builders should be better rewarded for their heavy duties.

I support the idea of giving the hospital more functions. The doctor should have more tasks in the hospital. Also, the hospital should be a place for recovering for the sick AND the weakened. I noticed that several villagers "weakened". I learned from the log that those villagers weakened because they had accidents during research or cutting the vines). By eating a stew, they got stronger again (I think the doctor should have a task here (dragging the doctor onto a weakened person does not result in healing). Maybe the hospital could be located near the pond, so the sick or weakened person can recover in the hospital, helped by taking baths in the mystical water and by herbs supplied by the doctor.

I think the maximum population of 90 people is too crowded. I never want a population of over 40-50 villagers.

For the rest: I am among the players who don't want too many changes. I like the general feel of the game.
