I do most of my coding during the many quiet spells at work. As you'd expect we can't install software on our work PCs so I don't have the luxury of being able to use an IDE.
In the past I have used a browser based ftp client such as net2ftp.com to download the file I'm working on, modify it in Notepad and then upload it for testing.
As such, I started work on an ExtJS based, tabbed, web server housed, text editor.
I will aim to put updates here as I reach definite milestones.
