      Dolphin contains plenty of productivity features that will save you time.

Dolphin's right-click menu provides with many quick actions that let you compress, share, and duplicate files, among many other things. You can also add your own custom actions.
      Dolphin is very lightweight, but at the same time, you can adapt it to your specific needs. This means that you can carry out your file management exactly the way you want to. Dolphin supports three different view modes: a classic grid view of all the files, a more detailed view, and a tree view. You can also configure most of Dolphin's behavior.
      Dolphin can display files and folders from many Internet cloud services and other remote machines as if they were right there on your desktop.
      Dolphin also comes with an integrated terminal that allows you to run commands on the current folder. You can extend the capabilities of Dolphin even further with powerful plugins to adapt it to your workflow. You can use the git integration plugin to interact with git repositories, or the Nextcloud plugin to synchronize your files online, and much more.

      exactly that as easy and pleasant as possible, and to simply get out of the
      way and let you read your comic books. One could say that it allows you to

      and effortless as possible is to allow you to simply pick up where you last left
      off. The welcome page in the application (first screenshot below) shows you your
      most recently read comics, and shows your progress through them. To pick up
      where you left off, simply tap the top left item and you will be taken right to
      the page you were reading before you had to stop.
    
      Features:
      
        Comic Book Archive (cbz, cbr, cb7, cbt, cba)
