Fresh was born on that sinking feeling we have whenever we head into the Finder to 'Find' that file that we are working on, just downloaded, or like to keep handy.
There are two main areas in Fresh. The top one shows files that Fresh has identified as new to you, currently being edited, etc. When you download a file from the Internet, or save an attachment in Mail, or edit a file in Word, it will show up here. As new and changed files appear on your computer, then are added to this area. If you click on an item, then press the delete key, then that item is simply removed from the list, with the file on disk left alone. To throw a document into the trash, just press 'command - delete' or drag it to the trash can in the dock. Since new items will be appearing in the 'Fresh Files' area all the time, if you see a file there that you will be working with today, just drag it into the 'Cooler' below.
The 'Cooler' on the bottom is a like a shelf where you can put things for storage. In this respect it it sort of like your desktop - with two important distinctions. One is that the files listed in the cooler can be anywhere on your computer. The other is that this cooler features an 'autoclean' function - it automatically throws out items that overflow. This means that you don't have to worry about cluttering up the cooler with too many items. All of the items shown in Fresh are really pointers to the actual files, so don't worry when something falls out of the cooler due to disuse, it won't really be thrown out.
Fresh can tag files - to tag a file simply select it (or multiple docs) then press the return key. You can pick from recently used tags, or simply type in tags. To move onto the next document, press the 'tab' key. You can also rate files with 1 to 5 stars. Spotlight searching for items that you have tagged is easy, just bring up the search dialog (command - F), and then click on or type in the tags you plan to search on. Search results are displayed in the Finder for further fine tuning or browsing.
