With FlashBuilder it is quite easy to work within the mxml file due to the code completion feature. The same holds true when I try to use code completion for any css files that I'm including in my flex apllication. But often enough, without switching to a css file and trying to type out the name of a property and seeing if there is a code completion for it ... I don't know which of the properties can be moved to style sheets and which can not. I could ofcourse refer to the docs but that is an even slower process.
Does adobe or any one out there on the web (that you know of) offer a tool to look over all the *.mxml files and spit out a list of all the attributes/properties that one could afford to move-out into style sheets?
