I also need this feature. I take picture with an action cam at 1-second interval. Sometimes it seems that picture and location are not totally synchronized. For example a picture taken at time t will appear at the t+1sec or t+2sec location. So parts of the sequence are shifted.
It would be nice to have a tool to select those images and to be able to move them forward or backward within the sequence. Ideally, I would like to click on the first and last pictures I need to move in the sequence to apply the change. So, not necessarily all the pictures of the sequence or only one picture in the sequence, but all the pictures between two selected pictures.
I would also like to be able to manually move all pictures between two selected pictures in a sequence, but that is another tool…
