This simple note-taking program for Chromebooks is great for quickly getting ideas down.
Its minimalist approach provides just enough features. You type your notes on a yellow legal pad template. It uses a single sans-serif typeface, but you can use the key combos of Control I, U, and B for italics, underline and bold. You can add images, but the app doesn't support drawing.
Notes are automatically saved locally; the file is named based on the first words typed (although you can rename it). The most recent item comes up when you start Quick Note while a list on the left shows the others.
At any time, the notes can be copied and pasted into other programs or synced via the Diigo file-sharing service.
