It does not use your previous stamps
AVG assumes the full screen to be a threat (although I can still allow it)
Preview pictures are really low quality and pixelly
Preview pictures when moused over do not show

Not bugs:

I think INSL, SHLD, and IRON should be moved to electronics. Iron can be used electrically to separate water, shield can grow with spark, and insulator can stop spark flow and is used mostly with electrics.
And why not add a gaseous nitrogen? Where does the liquid nitrogen go?
Copper would be cool, if it is surrounded by saltwater, solid salt crystals can form on it, it could have many other uses, but this is most interesting.
I also think you should be able to set the types of soap. It says "SOAP (GUN)" in the corners of a bubble, but you can't use gun on soap like you can with clone to set its type.

You don't have to read the not bugs if you don't want to (or if you refuse to read or think what they could be for, and you want to argue about them, you should just leave immediately without replying at all because arguing is rude and the last thing that anybody needs)
