Adding, moving and resizing tools

1. Pick a tool from the toolbar at the bottom of the board.
2. Move a window by dragging its top bar. Resize it by pulling an edge or corner; everything inside grows or shrinks with it.
3. Click × to close a window.
4. Use the small teal tab above the toolbar to hide or show the toolbar when you need more space.

You can open several Notes at once; every other tool opens once and comes to the front if it's already open.
