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.

Pluma is also extensible through its plugin system, which currently includes support for spell checking, comparing files, viewing CVS ChangeLogs, and adjusting indentation levels.
