Justify alignment can only, maximum, center 2 widgets when starting the process.
All widgets left to right are: Application Menu, Global Menu, Color Picker, Currently Playing, Color Picker 2, System Tray, Netspeed Widget & Better inline clock.
Whenever I reboot or kill & restart the process it only holds 2 centered things with justify.
Example using latte spacers to show it clearly can hold more, just doesn't load it initially.
It can also pull widgets from the side & center it when it wasn't placed that way.
