Multi-line taskbar applet for Cinnamon (Linux Mint)

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

Installation

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)

Configuring the applet

1. File applet.js contains a few constants, which you can adjust to meet your wishes:
   • TASKBAR_ROW_COUNT: number of rows for the taskbar
   • MIN_BUTTONS_PER_LINE: minimum number of tasks on one line, before we start filling in the next line
   • TASKBAR_ALL_WORKSPACES: shall the taskbar include windows from all workspaces (1) or just from the current workspace (0)?
   • TASK_MIDDLECLICK_ACTION: behavior on clicking the middle mouse button: 0=close window (old style), 1="clone" (Windows-7 style)
   • PANEL_ICON_SIZE: this is for the spinner when loading
   • DEFAULT_ICON_SIZE: height of the tasks themselves
2. Restart Cinnamon to see the changes

Known issues

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