Official branch's Unity Previews add proper previews for video clips, images and PDF files
Unity Previews are a new exciting addition that is to probably land in Ubuntu 12.10 in the near future, acting as hassle-free intuitive preview actions, available 1-click away, basically, right-clicking on a Dash item, opens it in a fancy preview with a big-sized clear image and description.
Days ago, the Previews were published in an official launchpad branch, being usable for applications and music tracks (from Ubuntu One Music Store), displaying specific content for the mentioned items, yet "ignoring" other item types, such as images, text files, folders, etc.
The latest development updates landed in the Previews' official branch, introduce a "global" exciting approach, meaning, right-clicking on a local image, opens it its preview mode, displaying the actual image and numerous details (such as name, creation date, format, size), allowing the user to properly observe the image.
While observing the previewed image, the user can 1-click away utilize the available actions, such as
Show in Folder (opens the image in its folder),
Open (opens the image via its default file handler).
The "full" preview mode has been added to images, videos (with big-sized preview), PDFs (with accurate preview), yet, documents, archives, music tracks, etc, can be opened with descriptions while presenting their icon as image preview.
The mentioned additions are definitely interesting, proving that the developers are planning to enable the Previews not only for applications and music albums, but rather as a global approach, where probably all the Dash items are preview-able.
Unity Previews have not landed in Ubuntu 12.10 (yet).
