The mod is already great, simply because it supports horizontal portals, but some manner of redstone control would be nice. Preferably some way to simply toggle the portal on and off, but if you're feeling adventurous, perhaps a way to change the portal target would be nice too. Might be too difficult through redstone, so perhaps some ComputerCraft support?

If I'm being too inchoherent: The feature request is for adding redstone on/off toggling support to the portals so you can turn them off and on using redstone.

I came here to suggest the same. It could all be done via redstone signal level, 0=off, 1-8 activate and select destination, 15 = activate and select default destination. This way anything could control it including ComputerCraft. Could also emit a redstone signal from the energy cell for charge level 0-15 (0-100%).
