You are right about the documentation, it's not all there. But if you follow Neilo's add on instructions, it makes it easier to understand.
The table thing, I brought up awhile ago. They have since applied a fix to the product, but I think they must have forgotten to apply it to their demo. I am on IE8 and I don't get the overlap now. But I wish they would have customized the table properties some (cell merge, and stuff like that) because whereas it is functional...it's still a little goofy.
I agree with you completely on the point of not applying the fix for images to the finished product. To me, that is just plain lazy.
All in all, I would say this is cms is one of the better one's on the market. Once you get past all of the initial "issues".
