In vanilla there is this global utility function ::Const.UI.getColorizedEntityName(actor), which takes an actor and returns a colored string.
It is usually used for creating the log entries in the combat log and with reforged we also sometimes use it for tooltips.

Proposal

• When using this function (or a new similar one), the returning string will not only be colored. It will also contain the metadata to become a link, similar to nested tooltips

How this link works

• While you hover over this name, that respective entity on the combat map will be highlighted.
• If the entity is dead, then its corpse will be highlighted
• This highlighting should the same way as when you hover over those entities on the turn sequence bar
  -> A yellow arrow over their head
