Adding additional lines (if more than 1 is possible?) would be an awesome way to organize nametags, for example, one could have PlaceholderAPI to have a player's guild/faction on the second line and show the player's health on the third line.
I used to use other plugins to provide this (at least for health) such as HealthBar, but it's quite outdated as it's abandoned and it's incompatible with some plugins I (and likely many others) use.

Please add this
