That is pretty well known, it's just during important fights you pretty much have to keep your focus on the party list and AoEs. Generally people keep their hotbars at the bottom of the screen and it's just not ideal to be looking for those tiny numbers.
What would be absolutely amazing is if there was a way to set how many yalms you personally would want the greyed out feature to show, but I highly doubt that'll be the case. Still it's a start, and a nice one nonetheless.
