Possibility to add labels or fields to the hover summary?

Hi! Thanks for making this available. Is there anyway to add a custom label to the flow or add additional fields to the tooltip/hover summary info?

Hello! Yes, it would be great to have a possibility to put an extra text in a tooltip/hover. Would it be possible? Thanks a lot for a cool plugin!
