I'm sorry you still haven't understood the main feature of this plugin.
I can align images (somehow) in Photoshop, Ngimp, and a bunch of other editors.
But they don't have what MOI3D has: dimension lines, guides, and the ability to precisely align an image to specific parameters. I'm a little tired today, but tomorrow I'll record a video showing how it actually works.
By the way, I've been using it all day – incredibly (for me personally) fast and convenient.
