This editor is quite useful for users with programming background. Support for keybinding customizations is amazing. The UI is quite minimalistic and is a great substitute to notepad in ubuntu.

The date and time insertion option is also good here. and data is auto-saved so that there is no fear of losing data that is present in the file in case of power failure.
