### Problem Description

DeArrow sometimes changes video titles unnecessarily, replacing fun/whimsical titles with plain/boring ones. It'd be nice to be able to control this.

### Proposed Solution

DeArrow now has a ['Casual' mode](https://wiki.sponsor.ajay.app/w/DeArrow/Casual_mode) which you can enable to keep some original video titles.

Can we add this as an option to FreeTube, to choose which mode DeArrow uses?
