If you're in the need for an easy way to concentrate your focus when writing, here's a tip. In Springpad, create a new note and then press Ctrl-F and F11. Ctrl-F will take you to the full screen editor for the note and F11 will cause your browser to go full screen, hiding everything else. Since the notes automatically save you can now concentrate on your writing. When you're done you can share directly from the note or just copy and paste your draft content into whatever destination you desire. Yes, it's just that easy.
Bonus tip: Use the [Ctrl +] and [Ctrl -] combination to make things larger and easier to read as you're writing.
