Hello Mike.
You plan to add the ability to specify in the article a link to page of portal, other View Page or externel url. This would significantly increase the functionality DigArticle - made it possible to record all portal pages in categories and tags, to show in ArticleList.
It is small additional, but in combination with the ability to specify for each category of your listpage control over the content becomes more complete.Now, if I want to add an article to any module (sample, flash-demo of product, or links with descriptions on other product serries), all the advantages of DigArticle lost.
If you're too busy, I can help with the implementation of these opportunities.
Thanks
Naviy
