That’s a great suggestion, Frederiko. I agree that Evernote has its place, but comparing DEVONthink to Evernote merely because both allow document collections doesn’t do justice to DEVONthink.
May I suggest you and korm as participants in illustrating what DEVONthink can do. 
I’m very impressed by the approach taken by korm and you in developing an annotation script in the forum thread at Export an index of annotations to a numbers spreadsheet
The AppleScript dictionaries in DEVONthink Pro and Pro Office support the potential to automate many procedures and to extend features in DEVONthink such as the powerful tool created by that annotation script for collecting and analyzing information in a document collection. Your final version of the annotation script illustrates its use by an attorney to add notes and tags relevant to a case, a powerful tool for that purpose. As is, the script is general enough to serve a variety of purposes, and is of course customizable for other needs.
