Does anyone else find this to be the case?
One of the main things I still go back to the help files for is what the arguments of an object are, and more specifically, what order they are in.
Take [counter] for instance.
Max5's help file tells you clearly how many arguments it takes, what order they are in, what it is if there are only two.
In Max6 you see a couple examples, and they are labelled, but because of the ambiguous numbers used it's not obvious which argument is which, and either way, you have to infer the information, rather than it being shown.
And the 'details' tab doesn't explain it either.
I've run into other things like this, but this is the one that comes to memory easiest.
There's also the fact that the reference and similar objects are now 'hidden' behind the '?'. That one isn't as bad as the information is still there, just moved out of the way for some reason. (I guess you highlight how cool the tabs are in Max6, at the expense of seeing helpful information immediately).
The argument example is much worse though as the information is now gone, and that's a pretty important bit of information to go missing from a help file (clear statement of what the taken arguments are, and in what order).
