This CSS improves the functionality and appearance of Zen Browser's experimental Tab Groups.
Apply a background that matches the tab group color for a cleaner and more cohesive look.
Add a subtle border to enhance the visual separation of tab groups (requires background to be enabled).
Add an arrow icon to indicate whether a tab group folder is open or closed.
Color folder icons based on the tab group color to visually differentiate groups.
Customize the folder icon fill with your tab group color—or leave it empty, depending on your preference.
Have a line sowing where the folder starts and stops
