Description

Right now the Window buttons are used to be:

"left click" to open a window if closed or show at top if already open and "middle click" to minimize the window if already open

I would like to request to change the behavior of mouse clicks into

LEFT CLICK

• If window already open and on top -> Minimize window
• If window already open and not on top -> Show on top
• If window is minimized -> Show window

MIDDLE CLICK

• Open a new instance (new window)

[ I have Arch Linux (Antergos) and Xfce 4.12 ( xfce4-panel 4.12.1 ) ]
