One thing that I would like to see would be better coverage in the HelpFile. I have just been looking at the PB Functions Listing and see that there are 716 items listed, where there would only seem to be 672 in the help file you get with F1. As a result I have discovered EventwParam() that is not in the help file (apart from in the history if you search) which makes reading the mouse wheel simple, so that I now have scrolling text from the mousewheel in a text viewer that I had written. The point being that it would be better if we knew what we already had instead of finding them by luck.
I go away for a couple of weeks tomorrow, but when I get back the first thing I will do is look to see what else I have been missing.
