This is a clone of the original Cinnamon applet that adds support for a multi-line taskbar.

1. Download the applet and install to ~/.local/share/cinnamon/applets/
2. Go to Menu > Cinnamon Settings > Applets
3. Ensure applet 'Cinnamon Multi-Line taskbar' is present
4. Uncheck the default 'Cinnamon Window List'
5. Enable applet 'Cinnamon Multi-Line taskbar'
6. Go to Menu > Cinnamon Settings > Panel
7. Check 'Use customized panel size'
8. Set bottom height to something around 35-70 pixels (depending on your theme and number of rows for the taskbar)

1. File applet.js contains two constants: TASKBAR_ROW_COUNT and MIN_BUTTONS_PER_LINE
2. Restart Cinnamon to see the changes

1. Drag-and-Drop (reorder) functionality of the bottom bar might not work
