If your thought process is "someone should make X..." then your next thought should be "I should try and make X...".

Go give it a go and as a minimum, you'll learn something about why it doesn't already exist yet and in the best case scenario, you'll create something that lots of people find useful!

Actually, my very next thought would be "I should Google this to see if anyone does", because 95% of the time, someone already is.
