One script for all variables?

Just a quick question, I was wondering if it makes sense to reference my public variables through one script instead of having them spread out over my many scripts?

My thought process for this was that it would be, at least, more convenient for me to just look through one "properties" gameobject that has all the settings and tweaks for my various script, instead of having to search through all the prefabs and what have you to quickly iterate through changes.

Does this make sense? Or is this a big no-no in game programming?

Apologies if this seems obvious... :)

Thanks!
