I'd love to see a feature that allows me to line up multiple point groups- I have photos of a building which wound up split into point-groups- front, back and foyer couldn't be linked, but if I could rearrange and move the clouds, it would be great.
i recently also tried to synth a building.
when i redid the synth with many more pics to better cover the corners
the synthiness dropped ...
since you have pretty good idea which "orphan synths" that have overlap it would be great to be able to give that input to the software.
could be as simple as drag-and-drop one pic in one "orphan synth" to a good overlap with a pic in another "orphan synth".
