Plugin Help F3 and metadata

Hi,
I wonder if it was possible to show metadata as part of the F3 information, just as the colour and the type of the current block.

I did set metadatas on my blocks but I'm looking for a simple way to show them when looking at a Block.

I could/will implement it but I thought maybe it would already been displayed in the debug info.

Is there another command I could try other than F3?

Thx.
