I've recently come across this app called FilePane on MacWorld http://www.macworld.com/article/2465174/filepane-review-expand-the-power-of-drag-and-drop-on-your-mac.html
I really like the concept. Looks like it's a review of the earlier version of the app 1.4 Having visited the developers website, looks like it's improved alot (UI and more features).
Was wondering if someone here's using it?
