Heynote is a dedicated scratchpad application that functions as a large, persistent text buffer divided into blocks. Each block can have its own language mode for syntax highlighting and auto-formatting, and it includes a calculator/math mode with variable, function, and unit/currency conversion support. It also supports inline images with a lightweight markup/annotation tool, and multiple organizable note buffers. It is available as a downloadable app for Mac, Windows, and Linux.
