How do I reorder buttons in the window-list (taskbar) via drag and drop?

Question

I switched from GNOME2 to XFCE and miss the feature to re-arrange the window buttons in the taskbar (window list).

How can I make it working?

I use Xubuntu 12.10.

Answer 1

According to a bug report this feature was introduced in XFCE 4.6, but removed again in XFCE 4.8 for the sake of code simplicity.

Anyways - after some long discussion it was reintroduced and is available in XFCE 4.10 which comes with Ubuntu 12.10 - it just has to be enabled:

• Rightclick on an empty space of the task bar (or at the corner)
• Choose "properties" in the "Window Buttons" context menu
• Choose "Sorting order": "None, allow drag-and-drop"

Answer 2

xfce4-panel 4.12.0:

Right click on the panel -> Panel -> Panel Preferences -> Items tab -> Window Buttons

Press [Edit] button. Go to [Appearance] tab so you can change the sorting order to

None, allow drag-and-drop
