[RCU] Question about custom sound notifications in Roundcube

Hello,

I’ve been exploring ways to make webmail more engaging and user-friendly. One idea I had was to integrate custom sound notifications for incoming emails or specific actions (e.g., sending, deleting, archiving).

Does Roundcube currently support using custom audio notifications, or is there a recommended plugin/extension approach for this? I believe this could improve accessibility and also add a touch of personalization for users.

As someone who works with sound-related content (see https://soundbuttonspro.com/ ), I’m particularly interested in how Roundcube handles sound features and whether there are best practices for implementing them.

Thanks in advance for your guidance,
