I feel it's much more convinient to use the /is command as it's not a long command and there are other shortcuts you can use so you don't have to go through the GUI every time such as, /is home(teleports you to your island), /is warps(shows you your warps), /is missions(displays missions), /is upgrade(shows island upgrades), etc.
so in my oppinion I don't think having an npc to issue the /is command for you would be beneficial towards the server but I'd love to hear more on your side.
