I am using TeXnicCenter mainly in fullscreen mode. However, I am not a big fan of it since I use this mode do keep off any distractions. Therefore, I am a really big fan of Writemonkey which can be found here: http://writemonkey.com/ I allows perfect fullscreen editing. It would be great if TeXnicCenter had the same feature.
If you have time it would great to see this feature. Keep up the good work. It is really appreciated what you guys are doing!
