This mod allows changing the visible name (and tag) of any player.

Commands:

/pt_setdname <name> - changes player's display name. Supports color codes! (Use &x, where x is the color code). The empty name will reset the display name back to normal.
/pt_setdtag <tag> - changes player's display tag. This is a slightly smaller line under the name of the player. The empty tag will hide it.
/pt_toggleaname - Toggles the visibility of actual player's names. (Draws 1 line more, above the display name)
/pt_hidenames - Toggles visibility of the whole name system. (Prevents player names and tags from being drawn)

This is a request mod (by MrLololoshka) so it may not update. But things change, inspiration comes, and stuff happens...
