This adds an extra button to the Youtube playlist.  Clicking it will remove the max-height limitation on the playlist. This allows easier browsing and dragging and dropping to reorder the videos in the playlist.

<img width="419" height="121" alt="image" src="https://gist.github.com/user-attachments/assets/d0adec9a-811e-48f6-b40d-2289b7aec02e" />

The arrow is the new button, which toggles the height from unlimited to 600px.

Use the `inject.js` in any JS injection tool for Youtube.com.  I personally like "[User JS and CSS Script and Style Manager Extension for chrome](https://tenrabbits.github.io/user-js-css-docs/)".

Enjoy!
