I am personally quite happy using just the Finder and Spotlight to find and keep stuff organized on my Mac. However some people prefer to have an organizer like Together to handle all their files.
This application will store anything, be it document, video, image or more. The application offers you a wide choice of ways to save all these, whether by fitting them into groups, labeling, creating smart lists or even adding notes.
You'll also always be see the exact number of items in each area from the sidebar of the program.
To help you keep your items organized, Together has a shelf side view, into which you can drag and drop elements and jot down notes.
It luckily also integrates Spotlight, making it really effective at quickly finding anything.
You can literally browse and organize everything without ever leaving Together's interface.
New items will open up in tabs, which is either annoying or useful, depending on what you want to see. I personally would like to be able to control tabs how I want.
Together also includes an embedded browser to preview bookmarks and links, which is more or less like a simplified version of Safari. Importing is fairly quick most of the time and you can see files being added to categories in real time.
