While playing I've written a few things down, that I would love to suggest. The suggestions ranges from QoL implementations and updates to the existing gameplay, to new features, additions and implementations that should make the game feel even more realistic.
#Full suggestion list

1:
Arrows should have a chance of getting destroyed, when they are shot at something that isn't an animal. Etc. if I were shooting an arrow at a rock, the arrow would most likely break in real life. Therefore this implemenation would make ranged combat feel more realistic.
2:
It would be awesome to see blueprints for boat motors. Would make traveling between islands way easier, faster etc. This shouldn't be easy of course, and there would have to be more than 1 blueprint for the boat motor. This could be divided into 3 blueprints. Something like (1 - Propeller, 2 - Engine, 3 - Fuel container).
3.
Add wooden signs to the game, so that we can get better sorting. Signs that are placeable on the drop boxes. Perhaps also implement some way of using the signs scattered near the shoreline, so that they have some functionality.
4.
Make it so that the raft can drift away. In reality the raft would be able to drift away from shore, if not properly secured. See suggestion number 5!
