Hello there. I want to present you a new tool: Quake Live Config Editor.

http://quakelife.ru/tools/cfg-editor/

Done:
- powerful embed editor
- special syntax highlighting
- autocomplete (commands, variables, models/skins, texture modes)
- optimization (removes non-existent, readonly, cheat-protected, server, outdated, default, dublicate, useless variables)
- sorting
- keep your scripts (optional)

Todo:
- built-in tooltips based on http://www.regurge.at/ql/
- comparing configs
- improve syntax highlighting
- recommendations
- visual preview
- support for other Quakes (?)
