Fresh is a small, low-cost, file-management utility that essentially offers an amped-up version of the Finder's "Recent Items" lists, along with a quasi-replacement for your Desktop called "The Cooler."
The app's streamlined interface consists of two simple "zones," or panes, which display your "Fresh Files" (basically, anything that's new to your computer or recently changed) and "The Cooler" (a user-defined collection of files that you want to have quick access to). "Fresh Files" is particularly great for tracking downloads and Mail attachments, and the Cooler can come to your rescue when you want to keep tabs on important files or folders. You can also pull up contextual menus on items to reveal them in the Finder (or just see their path), and you can control which files Fresh displays here, too (for example, if you don't need to see .log files, you can have Fresh suppress that extension--or you can have it ignore particular files or folders).
You can pull up Fresh's two zones the way that you pull up any app (for example, through the Dock or by Command-tabbing through apps), or you can use a customizable hot key--and the app's near-invisibility is one of its greatest assets. Fresh also has a hidden tab on the right side of the screen that you can drag files to, for placement in the Cooler or for tagging (Fresh has an optional, searchable tagging system as well).
As with all productivity-enhancing apps like this, Fresh may or may not jibe well with your workflow, but it provides a lot of easy-to-use and potentially time-saving functionality in a sleek, seamless package.
