"howText" EDITOR
This app is excellent for editing very heavy texts, especially if your browser has been supplied with adequate DOM Storage. I write single-file web pages which contain millions of bytes for the embedded images encoded in base64, and howText remains 100% agile when I edit them. Unless you are using a special text editor such as Sublime Text, you will find that heavy web pages are sufficient to slow down, or even break, an ordinary text editor.
