Fishing bowls/aquariums for storing fish and brags
Make us able to find or create fish-bowls and aquariums where we can store our catched fish or other sea creatures (perhaps in future updates) which then also can provide as a food ressource instead of having to stack fish in our bags where they would rotten (realisticly) away...
Ofcourse i also imagine us being able to see the different species swimming around inside of it.
That's a feature i had gotten to think about while fishing for dinner myself
