Hi Michael,
this is great!
This is even better than what I had in mind, since you take care of the whole alignment (scale and rotate) at once.
If it would be possible to add this to Moi, it would be a huge help when working with references.
Hi okapi, I'm glad that will work for you - yes I should be able to add this in for the next beta which should be ready pretty soon. That was actually a screen capture of it working inside of MoI right there.
It will be a new button that will show up here:
When you have multiple images, the one that will be edited is the one that is highlighted in the list, so that part is a little different than dragging images.
it is actually a special part of the Image command that you activate by pushing the new "Align" button in the Image options panel.
It isn't activated by doing anything on the edit frame, it is a totally separate thing from that.
I do want to add an additional kind of align/orient tool for objects as well though, but again it will likely be a new transform command and a separate thing from the edit frame.
