fccinter, there is no good method for doing this in 1.6.8. http://expressionengine.com/docs/templates/template_library.html gives you more information on what the Template Library is all about.
I use the /themes/site_themes folder to create a different look and feel for each site. The install creates a folder called default. Look through it using your ftp program to get a look and feel for it.
I then make for example, the folder name of blue (the site has lots of blue in it.
Inside my folder, I put in an images folder, and store images for the design there.
If I’m doing an html based design, I copy over the design elements there so I can view what the original templates had in them.
Once I finish the conversion of the html to EE code, I then delete the .html files, but leave the .css and .js files there.
Does that help?
