Hopefully I've recieved the full context for lasso use, but no where does it seem obvious the ability to copy a completed lasso path and paste it onto another image, you can only copy' paste the cutout of the image it creates from the selection, what if there was a way to copy just the outline? I believe it's possible because using Actions has shown me the points they create are saved (once completed), similar to the pen tools.
Another topic, that merges well, what if we could change the draw/eraser "head" to the exact proportions of a completed path (any kind) and use it at will (through means of a new tool perhaps)?
For personal needs this is useful because then I can make quick work of the many images (500+) I have pending manual editing, by halving it; I'll be re-applying from one photo with a"cloned path" once for every other image I have stocked in my folders. As it is now, the time between each photo (2) is 3-5min for a total of 6-8min each and every time. If by implementing these features, then the time to complete would be 3 or 4min in total; since the second photo would be as simple as the click of a button (or a few, you get the idea).
