As was seen in the BG 3 first gameplay video, sometimes in non-combat situations, you have to make a skill check which has on-screen a visible d20 roll. Sometimes you have advantage or disadvantage on rolls. The suspense of waiting to see what the final outcome will be can be exciting. Whether you like, hate or are ambivalent about Critical Role, the drama based around that can be thrilling. Moments such as "Good thing I have advantage because that was a natural 1" or "Natural 20, m-fker!" "Roll again, 'cause you have disavantage!" "...2, m-fker" are exciting.
So, in the circumstance that you have either an advantage of a disadvantage on those rolls (at least for the non-combat ones), I would like the game to display both die rolls, before the highest one for advantage (or the lowest for disadvantage) gets highlighted and the one not selected gets a little dimmer. Possibly even go a little farther, and have the dice rolled at slightly different times, and have the roll which is NOT going to be chosen resolved first about 60-65% of the time, so you see it slightly before the one which it will finally be.
This will not be confusing for the player because the game is going to explain Advantage and Disadvantage in the tutorial and help screens, and display "Advantage!" or "Disadvantage!" along with the die rolls. (If that's not enough, you can, in small text include "Advantage/Disadvantage: Roll two d20, taking the highest/lowest".)
