quicklook

quicklook is about the one thing its name promises: opening a file fast enough to glance at it and move on. That makes it useful for people who deal with lots of files and do not want to launch a full app every time. By our assessment, the main advantage is speed of inspection, not editing power, so it works best as a preview layer rather than a destination for real work. In practice this kind of tool feels light, almost invisible, and that is the point. Compared with full viewers or editors, it gives up depth in exchange for quick access. quicklook is strongest when the user already knows what they are looking for and only needs a short look before the next step.
