Need help with reducing padding

[pkese]

Hi,

I'm wasting a lot of horizontal space with very wide horizontal padding between icons.

I think we could fit twice as many icons (or leave more space for window switchers) if there was an option to reduce that excess space.

Is there a way to reduce that?

Does anyone know which CSS or UI schema tag is responsible for that?

You don't need to search into CSS or whatever to change that...
Just go into Dash-to-Panel Settings > Style... Change App Icon Margin and App Icon Padding.
Example:

You might want to change the App Icon size also... You can achieve that by changing the Panel thickness, in Dash-to-Panel Settings > Position...
