Four Wishes for FLEX 4

Don't get me wrong; I love Flex.  I think it's the greatest thing to hit the internet since email. But for now I'm going to focus on the 4 things that I hope Adobe will change with the 4th incarnation of Flex (which I believe is scheduled for release by the Fall of 2009).

PrintDataGrid - After messing around the PrintDataGrid for days, I came to the   conclusion that it just doesn't live up to it promise of easy, customizable printing.  I racked my brain for hours each day trying to get even the simple functionality to work (such as keeping the rows from breaking between pages, which is supposed to be taken care of by setting a single property).  In the end I had to make my own printing component for dealing with tabular data.  I recently discovered that Flash Player 10 is supposed to greatly enhance the printing capabilities of .swf files.

HTML control - AIR has one, why not Flex?  You can do just about anything with the controls that are available with the Flex framework, but there are times when it would be really nice put some html into the mix.

ItemRenderers - They come in handy, no doubt about that. But you have to jump through some hoops to get them to work properly.  It seems like every time I add a new code sample to this section of the website, its about how to get an ItemRenderer to behave.

FileReference control - It doesn't allow you to send parameters along with the file you are uploading, which makes it a little tricky if you want to do something like renaming the file before you save it on the server.
