[FEATURE] Search Field for Multiplier page

[jordan-dalby]

Is your feature request related to a problem? Please describe.
Finding settings in the multiplier page can be a problem.

Describe the solution you'd like
A search bar that can be used to find settings.

Describe alternatives you've considered
The only alternative is manually searching through the settings.

Additional context
From a developer standpoint, I suspect this will require a lot of work, and a lot of rejigging of existing code to allow for searching functionality.
