actualy, I have a better idea. rather than leave the map as it is, and add the marking system, the map should be an item!
if you have a map, you can read a map with m, but if you have to mark wich map you're useing or something... like say "/setmap dustari 298347873" or so... also the maps should be able to get titles and you can change the title of the map (if you have 2 maps named... say... "baka" then there'll be a baka [1] and a baka [2], and the numbers will go away when you only have one map named baka).
then if you have a pen, you can add/ remove flags from the map...
say, /add flag /remove flag and then a gui with a little pen-like icon that is positioned at the mouse's x,y will make a flag when and were you click... and if you have litaracy it will let you name the flag. likewise if you do the remove flag command you'll see the eraser end of the pen(cil)
also, maps should be bought separately for each island rather the according one is set when you go there
just don't have tingle sell the maps and we're cool!
