I have used Dreamweaver very little. However, I do find that using third party tools are best for dealing with a program s tasks that are outside its main focus.
For example:
Typically the third party tools are better and more efficient at performing the task than those built into the IDEs.
To me its a bit like going to a convenience store to buy groceries. You can do it but its not as efficent and its not the main purpose of the store to do so.
Additionally, learning how to use the tool outside the context of the problem will mean that you can apply and reuse the new knowledge to tasks unrelated to DreamWeaver. In summary: you are doing yourself a huge disservice for the sake of a small convenience.
