I was messing around with the panel icons and suddenly all the panel icons that were on the left side of the panel quite far from the windows came right next to the window buttons. I’m running the latest stable version of Manjaro XFCE.
I’m not sure what you have on mind. Did you delete separator? In Separator Preferences, you can set it to be expanded.
Can you illustrate?
You can also move some back to where they were by right clicking the icon. Then choose ‘move’. Move it to where you want & left click.
