4 years ago I'm a little hesitant here on the wording. So yes, a 1 always misses and a 20 always hits, and I can (and was...) show the roll as being green on the highest result of a die and red on the lowest result on the die. However, rules as written they aren't critical, they just always hit or always miss. Criticals are a commonly enough used house rule though. What do you think?
Without hovering over the the attack roll result, it is not clear whether a roll was an critical hit or miss. A rolled '1' is always a Miss and a '20' is always a Hit independent of the targets AC. I think it can be easily overseen, because you always see the end-result and not the dice-value.
I'd suggest a message like "Critical Hit!" or "Critical Miss!" that is visible in the table that shows the attack and damage roll results.
