3D cursor

I'd like to thank the dev team for this amazing DICOM viewer. Definitely the best out there.
I want to suggest a feature that, to me, would be very useful. Currently, when I use the 3D cursor, it shows me where that point is located in all other panels, including 2D reformatted images. However, if I use the 3D MPR on a series, it opens a new window, and I can't make correlations between the 3D reformatted images and the other regular images, located in the panels. I'd like to know if it's possible to make the 3D cursor work with the 3D MPR.
I have personally ran into many use cases in which this feature would be great, but I'd like to mention a few:
a) CT angiograms always need to be 3D reformatted, but sometimes it would be useful to click on the 3D MPR post-contrast image and see where that point is located in the pre-contrast series.
b) In one hospital, I receive the pre and post contrast axial images of head ct scans. However, the tecnicians never position the patient correctly, so I always need to realign both series in the 3D MPR in order to get proper symmetry. Sometimes, I would like to be able to click with the 3D cursor on the post-contrast image, and see where it lands on the pre-contrast series. In this case, it would need to make the correlation between two 3D MPR windows.
c) When evaluating rib fracture, volume rendering is very useful, but sometimes I'd like to be able to use the 3D cursor in a point I suspect is a fracture in the axial image and see where that corresponds to in the volume rendering image.
I understand this last one might be harder than the others, but simply making the correlation between the 3D reformatted images and the non-reformatted one would already be an amazing feature.

Lucas, thank you for your kindest words!

In future versions we plan to improve the 3D cursor functionality and make it work across the 2D, 3D MPR and 3D VR viewers. All the cases that you listed should be covered when we're done.
