Hello, thank you for your PR! NewPipe is currently undergoing a refactor on the refactor branch, and we are rewriting the UI there, and not accepting any more non-strictly-necessary PRs on the dev branch. We are switching from XML to Jetpack Compose there, so it would be good if you could maybe rewrite some simple components in Compose on the refactor branch, and while at it also embrace Material 3 (which is the default on that branch)!

Since I have raised a PR for the Material 3 migration, I will close this one.
