Sublight is a popular multimedia application for searching and downloading subtitles for movies and TV Series.
It provides access to numerous (millions) subtitles in 46 languages eliminating the need to open up different websites for downloading subtitles one by one; you can just implement Sublight and downloading subtitles becomes effortless and centralized.
One nice function that is included within Sublight (among many others) is the automation of repetitive tasks; this allows you to move on to more important things simply by double-clicking. You can also fully maintain your personal list of previously seen movies and shows. If you have the time, you can publish your custom-made subtitles making them available to the Sublight community - this is a two-way street where you can benefit from someone else's produced subtitle.
