To be an antagonist here, I disagree with you on the difficulty level G'Kar
If you have previous coding experience you should find the ability to use the program much easier than if you are strictly WYSIWYG without any coding experience or very minimal by just inputting code for a script you're using. The reason I say this is that you need to have some type of experience and/or knowledge about CSS and how it's used to really understand how it works. If you don't it will most likely be a trial and error learning experience (which I don't think is impossible at all as that's how many learned the Shopping Cart Designer programs).
With knowledge of HTML and CSS you will already understand what the different settings stand for and will do for you without the trial and error ( well maybe just a little bit hehe), and things will pop into place a whole lot faster and easier for you.
Really the only thing that VSD will do for a user of this program is give them the similarity of drag and drop of elements, from there it's knowledge that will help a lot more than visual experience.
P.S. In the end though it's all doable, the learning curve may seem stiff, but although it may take someone longer that has no knowledge of coding, it is still very learnable with a little reading and some trial and error and some people *points to self* learn very well that way
P.S.S. NOTE: There is one thing that will be a very big issue for anyone that is coming from VSD to this program. You will have to have knowledge of web building in order to complete the site. This is only a Layout maker, not a site builder, so you will only have a structure and a few details entered into the program for the site. The code will need to be exported to be uploaded to your server, or published on S-Drive AND you will need to finish all the rest of the site manually using a web building program such as HTML Editor or Dreamweaver/text editor/etc. to do so. This means you WILL need to have some knowledge of web building code to use this program effectively.
Just my 10 cents
