I think it's totally fine the way it is currently and i don't have any problems imagining how a character would look like based on the descriptions.
Maybe one day if the character viewer will become a thing again, it could help people like you who have troubles with imagining things. I can hardly imagine it holding any priority over anything currently in development though. Which is the right way for it to be if i may add. This is a text-based game, if you don't have the proper imagination to immerse yourself in it i guess it's not the thing for you.
I would say it's a modern disease in my opinion. People read literature way less thus use their imagination less as well compared to back in the day when books held the only source of fantasy. There is a reason for why teachers and old people nag the newer generations to read books. They have a good reason for doing so.
I'm not saying that modern sources like video-games, movies and whatnot are a bad thing. It's just that you should also keep room for your own imagination to build for yourself.
