initial response: huh... interesting, BUT I don't really ever do the thing you seem to be using it for. I take lots of temporary notes, but i don't figure ideas out in text then blow them away very often. On the occasions when i do do something like that I rely on Markdown formatting a lot to help break the idea down into sections and emphasize things (tools like Byword and FoldingText which will bold the headers, make italics italic, etc.)
