Hi there

I'm looking for a clip&collect app akin to DevonThink, Yep or Yojimbo for research and material collection.
However although those three are great in their own right I need one that allows a short summary of an item in the database to be taken. Just a little pane that shows up when I click on the pdf or text or whatever in which I can take a brief note to remind me what's in the item and why I collected it.
Devonthink allows an annotation to be taken, but that has to be opened separately for each item thus defeating the purpose of a quick summary and the other two have no such thing (the spotlight comments pane is less than mediocre for this purpose).
So I was hoping someone of this esteemed community knew of such an app?

Thanks in advance
