I think there are enough tools available for this because I currently use phpdesigner for coding work and store all of my libraries inside there. Although I do not own a copy of dreamweaver, I think it has the same feature as well.Not a web designer, but would like to see more tools available that can help a 'copy/paste code' designer like myself create less crappy looking designs. Luckily for me codecanyon exists so I can just buy random elements I want to implement in a design as opposed to doing it by myself or buying a template.
