I have been using Linux Mint 13 and Mate, a desktop environment forked from now unmaintained Gnome 2. If you like to know more about Mate, visit the Mate Desktop’s website. Mate comes with Pluma, a text editor called based on Gedit.
Pluma is a text editor which supports most standard editor features, extending this basic functionality with other features not usually found in simple text editors. pluma is a graphical application which supports editing multiple text files in one window (known sometimes as tabs or MDI). Pluma fully supports international text through its use of the Unicode UTF-8 encoding in edited files. Its core feature set includes syntax highlighting of source code, auto indentation and printing and print preview support.
