I have a few ideas, I'd rather not spam you, and will submit the together. If you'd like them seperate I'm willing to correct my entry.

1. Add shift click with flask in inventory slot to empty the flask.

Sometimes I accidently contaminate a flask with bad water. It would be cool and in line with the mod to be able to empty the flask without having to go through a lengthy process or having to drink the bad water.

2. Add configurations by world and /or biome for the contamination chance.

There are mods that add water to the End. Also swamps should have a higher chance, while rivers a lower chance.

3. Add a large non-portable block, water barrel. Can hold like 50 drinks. If broken, automatically empties. Simply for storage of large amounts of water. An upgraded version where you add a spigot to allow drinking from it.

4. Add a copper bucket. Allows for the transfer of the water from a cauldron placed over a fire to another container (above water barrel, or a copper cauldron) without contaminating the water. Can't drink from it.

5. Add a steal or copper ladle, allows for taking a drink from a cauldron, water barrel, or cauldron over a fire.

Hope you like the ideas. Love your mod.

Thank you, appreciate it :) Your suggestions are pretty good.

The first suggestion is already a feature but the player has to hold the flask and shift right click onto water.

Maybe this could get added as a tooltip on the flasks? I had to find this Issue to realize this was a thing and none of my other friends figured this out, we just drank the non purifier water if we misclicked it.
