All the multiworld plugins I've seen (and there are quite a few) are either configured to allow only two worlds (i.e. normal and nether), or add extra capabilities that I don't want (like teleporting within one world). Does there exist a plugin which I can only use for creating portals between worlds, essentially like nether portal plugins but with support for any number of worlds (ideally with separate "compression" ratios too, like the 1-to-8 ratio for nether travel.)
