I love the look of the new micro bubbles.
Simply as a point of productive criticism, certainly nothing else because I'm a fan of your mods...
bubbles underwater do not form round bubbles as one would think of them being blown in the air. Rather, they form a semi-sphere, or disc shape (almost like a jelly-fish) that expand and break part as they rise.
Could you see anyway to work in bubbles like that?
Here's a pic of some realistic bubbles in the water (I hope I'm posting this pic right, never done that before. Also hope it's not violating anything, would a mod please let me know if this is not good)

edit: yep, well it didn't post the pic, but it linked. Guess that will have to do for now. Cheers Ailantd, good work!
