age range is tough in roles because each option is 10 years different but when casting a guy thats somewhere between 25-35, youre forced to choose between 20-29 or 30-29, and theres a huge difference between an actor thats 20 years old and one thats 30 years old, but not so much between a 25 year old and a 30 year old or a 30 year old and 35 year old.
if it can be changed to a slider we can more accurately select the range in which we want our actors.
That's an idea I can get behind too for those roles (ex: 18-24 range for that young adult in some movie, 55-69 for that role of some villain whose middle aged but not yet a pensioner in a show, 8-14 for a role in some animated movie that is not using grown people to voice a child character or a show for a kid.)
