There was an interesting update today to SEO PowerSuite which adds tags to all the programs in the suite. If you don't know this Suite yet, you should check it out – it has many interesting features that allow you to do SEO work automatically, such as Rank and Link checking, getting links, looking at links and other factors for pages and checking your own pages for optimum SEO.
This allows you easily keep group keywords, pages or tag them with important information. Looks very useful.
They have some screenshots that detail it in the article.
Check my review of SEO PowerSuite and Market Samurai if you'd like to know more about them.
