Hey,
I want to suggest something, it will be nice if we can made vertical portal, I d'ont know if it's is possible but it will be cool.

I'm going to have to agree that this would be very nice. I was on my way to recommend the same, but it's nice to see I'm not the only one who wants this.

Just imagine all the fun stuff you can do, like this.

There's more than that, obviously, but it'd enhance the mod if we could create vertical portals. And #29 and #30 play into this pretty well, #30 specifically. Being able to set it to receive only, would let you portal people into an arena they can not escape from for example, would be nice as a pack maker. Likewise, if this could be controlled with redstone -an extension of the suggestion in #28- e.g. simply toggled, you could also let them leave after they've beaten the boss so to speak.
