I’m working on creating a CMS (You’ll hear more soon enough), and I need a really basic textarea editor. The only things I need from the editor are:

• Backspace when you’re at the whitespace at the beginning of a line removes a number of spaces equal to your soft-tab width
• Command+left or home goes to the start of the text on the current line, rather than the beginning of the whitespace.
