Dolphin vs MythTV

As with any KDE app, Dolphin, allows adding or modifying toolbar buttons and keyboard shortcuts.

Dolphin supports splitting the view in two navigational areas, this way you can navigate two different directories at the same time.

Pressing F4 with any opened folder on a mounted path opens a console within dolphin.

Dolphin is without a doubt the best fully functional and easy to use and multitask with.
Dolphin also has a refresh button which no other File manager has. It's great for tracking a large files transfer; that's what file managers are for - good common sense.

Dolphin follows KDE's philosophy of being extendable and configurable. It can easily be configured and customized through plugins.

Dolphin automatically identifies and mounts external flash drives.

Pictures with or without previews is optional and selectable at the touch of a button.

Unlike all those GTK-based file managers it does not have to rely on external written software for its functionality because KF5 is KDE SOftware and developed alongside.

It starts with last opened folders.

Supports HiDPI displays.

In icons view mode, the space between files gets stretched so that there is never and annoying empty space at the right side of the window.

Pause, skip, and rewind live TV shows.
Completely automatic commercial detection/skipping, with manual correction via an intuitive cutlist editor.
Intelligently schedules recordings to avoid conflicts.
Parental controls to keep your kids out of the good shows.
