How do i get my hidden options back?

Ok i was actually done with my retroarch settings and games, so i hide a lot of options (like the core updater and a lot of other stuff) So i cant accidently change stuff or delete anything.

Is there a simple way to get those back without deleting my config files and start everything over??

Sure, anything you hide you can un-hide. Look in settings > user interface > views. If you’ve hidden the settings menu altogether, you’ll have to modify the settings in your retroarch.cfg.
