Dear Proton Development Team,

I'd like to suggest a valuable addition to enhance user engagement: the introduction of a "Reaction Tracker" button for folders. Here's a brief overview of how this feature could function:

1. Users can activate the Reaction Tracker for a specific folder within the Proton app.
2. When a recipient opens a shared video link from that folder, their face camera will automatically initiate recording.
3. The recorded reaction videos would be neatly stored in a designated folder titled "Recorded Reactions" for easy access.

This innovative feature not only adds an element of surprise and delight to video sharing but also provides a unique way for users like me to capture authentic reactions from friends and contacts.

I believe incorporating the Reaction Tracker for folders would elevate Proton's user experience, making it even more enjoyable and interactive. Thank you for considering this feature request, and I appreciate your ongoing efforts in refining the Proton app.

Best regards,
Atul Sahu
