This is very true, and kinda makes this product already seem obsolete if I can code in my favorite IDE instead starting this massive load of crap up. I don't think HTML5 needs an IDE such as this.
Flash was a wonderful way to learn about object oriented programming because you could literally draw an object and add code to it, as you described.
However, I think controlling objects appearances with CSS instead of the IDE or direct code that is mixed with other ActionScript is what finally converted me away from Flash.
The new CSS3 features were too good to pass up especially if I could use them for free and with any text editor.
