Quote from LombraI've thought of something else. You could store the GUID for each unit in the warn frame, and then use that to set a proper unit tooltip (using tooltip:SetHyperlink("unit:GUID")) on mouseover. This tooltip can also be used to extract the level of the unit, fwiw. I realise there already is a tooltip, but yeah.. just a suggestion.
Edit: Oh, and would an option to align the text in the warning frame be possible? (left/right)
Done. and Done.
