 default to the normal formatting, if not configured.
 With `{index}` the tab position can also be used. With `{floating_total_count}` you can print the total amount
 of floating panes.
+In addition to separate formats for sync and fullscreen tabs, you can use `{sync_indicator}`,
+`{fullscreen_indicator}` and `{floating_indicator}` in each format. It will be replaced with the respective
+configuration from `tab_sync_indicator` and so on. Please be aware, that the indicators are only replaced
+when they are configured.
