Hi,
I always wanted to have a way to display date/time, CPU temp, volume control when using MLD.
I found that nice application called Polybar, i compiled, installed it and it works great.
The only drawback it will displayed on top of other applications if you click on the maximize button of that application however it will be hidden in fullscreen mode.
Polybar repo:

Best Regards.
