Hey @bprusinowski Please find below my feedback in the screenshots. It's mainly design adjustments.

In general the metadata should be structured via the Textstyling. I think we could get rid of those grey lines and instead style the text as title and main text. Currently its a bit of a mix. See screenshots.

I'd also reintroduce the underline to make it more clear that metadata is hidden under some labels. Can we influence here the spacing between the underline and the text? The standard one I find a bit too narrow.

We could also try - instead of using the Textlink for the "Metadata" Label - to use a Secondary Contained Button to make the Metadata more visible.

I couldn't test the Metadata Panel in the published version as it always crashes.
