Making a simple "Control Panel" like desktop application launcher

[anon222]

It's a good idea.
You can make a multi-level launcher and drag and drop items from the menu to the folder where the launcher stores items.
Here is how:

• First open the folder where the panel item are stored. Notice launcher-8, launcher-9 etc. Those are folders where the lauchers are located. Leave the thunar window open.
  

Code:

thunar ~/.config/xfce4/panel

 

• Right-click on the panel then Panel -> Add New Items...
  
• Add a launcher right-click on the icon -> Properties and one random item and you will notice in the thunar that a new folder has appeared (for me it's laucher-13)
  
• In the advanced tab disable tooltips and change "Arrow button position" from "Default" to "Inside button"
  
• Open that folder (laucher-13, for you it might be different) and you'll see that there is a desktop file in there. Remove/delete that file.
  
• Now just drag and drop items from the menu to that folder.
   
       
  
• If the panel gets stuck for any reason just restart it with
  

Code:

dbus-send --print-reply --dest=org.xfce.Panel /org/xfce/Panel org.xfce.Panel.Terminate boolean:true

It should look like this:
