Allow admins to create ports that only teleport players if they're carrying a specific item with a specific damage value.

Agreed, having this feature would make it amazing and add a more rpg feel to it. For example, on my server we have a "Ticket Seller" NPC that sells redstone torches but in the off state so that users have to buy them. Requiring them to have that in hand and then when they step into the region the plugin removes it from their hand. Would love to see this!

I will work on this when I get the chance, but I have exams coming up in under a week :/
