Comment on Skim

Amazing! Skim is unbeatable for people who take notes in PDFs. You can search Skim notes in other apps, like BibDesk, Leap, EagleFiler, the Finder, and Spotlight.

Here's a tip for Skim users: download BSP and add Skim notes to it by clicking on + and choosing a .skim file. Now, whenever you use Spotlight, individual Skim notes will appear in a separate group in the search results. You can also create Saved Searches (a.k.a. Smart Folders) in the Finder to search only your Skim notes.
