I work on various projects that are under the KDE umbrella.
The Kate editor, a full-featured text editor
The KTextEditor framework, a versatile text editor component
The Syntax-Highlighting framework, close to 300 languages supported
Contributors to these projects are welcome.
If you wish to sponsor the work done by KDE in non-technical ways, please think about donating.
