=== Description ===
This userscript automatically clicks the "Show more" button in YouTube's subscription sidebar,
ensuring your subscriptions list stays expanded. It works by:
1. Watching for the YouTube guide section to load
2. Finding the "Show more" button using various selectors
3. Automatically clicking it when found
4. Retrying multiple times if needed

=== Installation ===
1. Install a userscript manager (like Tampermonkey)
2. Install this script
3. Visit YouTube - your subscriptions should automatically expand!

=== Support ===
For issues or feature requests, please visit the GitHub issues page.
