If there isn't anything like this already, I would like to see a mod that would make hydrating yourself a way more faster than it is now. The way how often you are required to drink in survival combined with the fact that you have to spend ridiculous amounts of time watching those pumping animations at settlement's waterpumps is a waste of time. It would be much better if:
A) you would get fully hydrated instantly while drinking from water sources that offer infinite amount of purified water
B) while you'd be inside the construction boundaries of a friendly settlement that has at least one infinite source of purified water you would be fully hydrated all the time you spend inside that settlement.
These changes would not make the game easier/harder, they'd just make the game much more enjoyable by getting rid of unnecessary steps.
I don't have modding tools set up nor do I know how to implement this, but if nobody decides implement this I am planning to try it myself. If you have any tips how this could be made possible feel free to comment.
Thanks for reading.
