We're happy to announce that we are are adding full width support in Notes. We've received feedback that working with tables with multiple columns is difficult with the existing layout. You will be able to expand the size of the editor area on your screen to full width with a single click. We've also made a couple moves to improve toolbar layout consistency. The strikethrough button will now be in the toolbar at the top, so that you have all of your font controls in a single place. The "Saving..." indicator will be moved to the bottom right of your note, so that it's always visible.
