I'll try to add this one at a time then. With the addition of the new Crewmate roles (Tracker and Noisemaker) I have thought of a couple ways Crewmate roles can be changed that use their mechanics.
#"Imposter" Crewmate Mechanic Change Ideas
robust stream
Medic can instead be assigned as a Tracker at the beginning of the game. This makes the role more beginner friendly for people that have never used mods before the combination of them getting the Imposter intro, a kill button, and the opposite meaning to the kill button (press the kill button someone so that they can't be killed for the rest of the game) can be confusing for some players.
weather or not it actually tracks the person they protected is up in the air 🤷♀️
Tracker can also be assigned to Lawyer and Executioner so that they will always have a tracker on their client/person they're trying to execute.
Moving onto Noisemaker
Roles like Bait, Celebrity, and Cyber can get this role witch people have already mentioned. But they can be distinguished between by changing the color of the icon/the icon itself/the sound the alert makes.
