This one is pretty obvious, but if the default scripting behavior is no longer going to be to create the if exists - drop statements, at least leave it as an option.  Our entire shop depends on that feature of EM. 

And along those lines, would it kill SSMS to remember my preferences from the last time that I scripted something?  There is a good chance I'm going to want to do it the same way each time and digging through all the options each time is a killer.
