As our README and our contribution guidelines (which you agreed) say, only bugfix PRs will be accepted. We have to close your pull request unfortunately as it introduces a new feature.

Here are some tips for your future pull requests on this repository:

• Please base your branch properly on top of the upstream dev branch. The first 4 commits, which are not a part of the upstream dev branch, have nothing to do with your changes and so are not necessary for them.
• Several of your commits seem to be "WIP commits". In NewPipe projects, we prefer generally cleaner commits so we can use them as they are when merging pull requests, allowing us to better understand PR changes in the future. You should have squashed some commits as they contain several unneeded changes at the end (like printing LOL to Java's standard output) and improved their wording (App Crashes isn't a good commit message at all in my opinion).

Please do not take this result as a bad experience but as a learning one :)
