Good day

I love the new uniform transform tool in Gimp 2.10. I do aerial photo overlays and it makes the number of steps needed to bring a different aerial photo over the top of an existing one, much faster.

However there have been some challenges which may or may not be an incomplete implementation at this time or perhaps some bug in the software.

More than once after completing the preview alignment I have forgotten to click the Transform button and gone on to another step and then discovered there is no way of getting back to transform. While you are in the transform preview you can undo specific steps, but as soon as you have gone out of the transform then there is no way of going back into the transform and retrieving it. Looking through the undo list none of those transform preview steps are in the undo list. As soon as you would accidentally go out of the transform tool it evidently just dumps all the individual steps.

I think the transform preview steps need to be included in the undo list all the time, not just when you are actually setting up a transform, because it is so easy to accidentally click the wrong thing and hey, it's just dumped all the stuff you did and you have to start again.

I see on further investigation if you click on one of the other things in the Toolbox it automatically carries out the transform. A few of the tools have similar behaviour like the Crop tool.

I'm not totally convinced this is the best thing for usability because again, accidentally clicking the wrong thing results in the transform or other action being carried out, which can be very slow, you then have to wait to undo it, which can also be slow, and potentially if the undo buffer is too small you might not actually have that undo option.

The main concern is the transform completely disappearing and you can't get it back, if you carry out some action like going into the layers list and dragging layers into a different order. I don't understand why the transform preview steps don't appear in the main undo list.
