It shows video progress when playing video on IINA, To let me know when the video ends instead of moving the mouse to check HUD, lol.
And forwarding/back-warding too.
I did find TB useless and gimmick but I admit it makes the keyboard looks cooler then a nonTB keyboard.
Do you know any Apps that makes the TB more useful ? Or some tips for using it ?
One tip I can give is to make the TB shows Apps Controls only, And pressing 'Fn' to show Control Strip.
It's much better this way for me.
