Konsole supports split-view which splits the window into two (or more) Konsole instances. This is very useful for people who work a lot on the terminal and don't want to spend time navigating between different windows or tabs.

In particular solarized.

Konsole can be embedded into desktop so it's always easily accessible, but not in the way of other windows.

Konsole can monitor activities and notify the user through system notifications when a certain activity happens. This is a very customizable feature too: you can write scripts that can use this feature and notify you for whatever you want.

Good menu to customize.

Konsole can bookmark ssh and telnet sessions, directories, and it can open tabs in a folder for easy access.

Most terminals in Linux don't support font ligature, while many modern fonts such as PragmataPro or Fira Code already have decent coverage of font ligature. Support for font ligature makes user experience and font management much easier (i.e. you don't need to keep two copies of the same font just to use in the console).

Konsole supports true color and smooth font. This makes Konsole more fantastic than other terminal emulators.

Profiles containing different settings can be created, saved, and loaded. Color schemes, window transparency, scroll bar, key bindings, start-up commands, window border, and menu bar can all be customized according to the user's needs.

Konsole is usually very fast. It boots up very quickly and takes less than a second (averages to 0.25-0.59 seconds) to display files of up to 600 MB.

Konsole can be accessed by pressing F4 in Dolphin, which is convenient for when the user needs to open the terminal in a particular spot of the file structure.
