My favourite features are
- server side resizing of images
- ability to develop multiple sections, subsections, and easily assign different modules to each section (this is a great way to land advertisers who may only want to advertise in certain sections)
- the fact that the initial template for the article page adheres to many current trends
- ability to add extra fields (such as extra title lines, extra information)
Now, to be fair I noticed one comment below that I agree with. The code does not render the web-page in IE the same way it does in Firefox. The difference is usually extra white space in IE. This can be a pain to account for when you are developing the site.
Other than this I'm really happy with this plugin and would recommend it to anyone looking to develop a newspaper/magazine website.
