[Feature] Add search option in settings

[David-Maisonave]

Is your feature request related to a problem? Please describe. I was trying to figure out how to import json (exported) data, but I couldn't find the option in the settings. Programs with many options will sometimes have a search button that will help the user find the option.

Describe the solution you'd like Add search button option to the settings menu, which would allow users to find location of options.

Screenshots

Example FireFox settings menu with search option.

Example usage FireFox finding settings associated with keyword password.
