Something I was wishing for the other day that I hope can make it into Logos 10 would be the ability to "attach" clippings and notes to a Factbook entry so they appear in the article with the other categories. It would be nice to be able to enhance a Factbook entry with my own articles (clippings) and notes rather than just creating separate note and clipping documents. This would make me much more likely to use Factbook in the future as it would grow in value as I add content over time that I find relevant to a particular topic.
As a side note, it would be nice if all resources in the store were marked with an icon or notation letting me know this resource's content will appear in Factbook if purchased.
