I love me some Eagle Filer.
I've been evaluating four major "PIMs" this past year and am working on a thorough blog review of them all, but for the record—Eagle Filer came out on top.
My only question at this point is: can the keyboard shortcut for Quick Look be changed from CMD+Y to the normal OS X-wide "space"?. It drives me nuts!
(and it can't be changed in the application specific keyboard shortcuts preferences because the menu item is dynamically named.)
Great work Michael! You're definitely one of the top developers in the hallowed halls of Mac apps.
