How Plasma/Kickoff app launcher always opening aligned horizontally to the center of the screen

[Konstantin Makarov]

Hello,

How can I make the Plasma/Kickoff app launcher always opening aligned 
horizontally to the center of the screen?

I know that if I place the app launcher icon (button) on a center 
aligned panel, the app launcher opens in the center position of the 
screen. But if the app launcher icon has moved to the left (for example, 
when started app icons pushing the app launcher's icon to the left) and 
app launcher's icon position going lefter of left border of the app 
launcher, then the app launcher is jump to the left from screen center 
and centered by app launcher's icon (is not in the center of the screen).
