### Problem Description

It can sometimes be hard to find something on the settings page

### Proposed Solution

(Fuzzy) search feature for the settings page

### Alternatives Considered

I think the individual sections of the settings page, that are hidden by default are what make the settings so confusing. An alternative would be to show all options by default, and have something like a table of content on the side, which allows the user to jump to a specific section.

### Issue Labels

ease of use improvement, new feature

### Additional Information

This is probably a duplicate, but FreeTube has over 2500 issues and GitHub's search is really bad.
