Question, currently I use Cart QuickNotes and a macro/button to note my target, but I have to use 2 macros/buttons for different colored notes in order to tell mob notes from other notes (red note for mobs and purple notes for everything else), is this similar functionality?
Similar, but there is only a single slash command. The type of note (including the color of the note's title and the icon for that note) depends on whether or not the targeted unit is friendly to you or not (the defaults are Skull=unfriendly and Diamond=friendsly, but you can choose any icons cartographer knows about--I use a CT_MapMod icon pack I put together (but have not yet made available for download)). In this case, the addon is making the decision about the note icon for you. There is another addon, Cartographer_QuickNotes, that supplies different slash commands to create notes with different icons/colors. Its goal is slightly different than mine.
