Hi @ClaesM,
Just to make sure we’re all marching to the same beat:
I’m one of the forum moderators, and @nerd is the mastermind behind V4. Everything we do here is squeezed in between our actual full‑time jobs, this whole volunteer gig is powered by whatever free time we can rescue from real life. So we pick fun things to tinker with and show what’s possible. Same story with PeppyMeter.
There is a perfectly working, fully maintained version from @balbuze, 100% functional, no drama. (For Metadata you can always fall back to MPD_OLED)
The version you’re referring to has always been a bit of a “pian point” (yes, pun intended). People love it, but it tends to break important parts of Volumio, like OTA updates. So instead of shipping something unstable, we’ve handed the building blocks to the community so everyone can experiment freely.
Just remember: plugins belong to the community, not to Volumio or its volunteers.
