One thing that is very important to me is the ability to import/export my data from any application. I hate being locked in to a single application - who knows when it might stop being freeware, or when the developer might give up development. Not to mention the fact that if you've spent a lot of time developing data in one application and you decide to switch, lack of an import function means wasting quite a bit of time! As of now, this otherwise nicely designed application offers no OPML import or export, so it gets a much lower rating than it might otherwise.
