Fairly simple Meteor Client addon to mark specific players as "enemies".
If the 'Highlight' setting is active:
- Enemies will appear as a different colour in the player list (tab menu) if the 'Better Tab' module is enabled.
- Enemies will appear as a different colour in nametags if the 'Nametags' module is enabled.
.enemy list: Display the list of enemies in chat..enemy add (name): Add user to the list of enemies..enemy remove (name): Remove user from the list of enemies.
The vanish checker works by exploiting a bug in some vanish plugins where a vanished player will not appear in the player list (tab menu), but will appear as a suggestion when writing a command. If the vanish plugin does not work in that way, it is better to leave the feature disabled.
