Excellent. This works great. Couple of points (you knew there would be).
Any chance that GAIA can automatically recognize it's been given a cube?
[so that you don't end up opening the cube and then having to open the
window and reselect the cube to get the slices]
Any chance of the automatic stepping through slices functionality that DS9
has?

I've just tried a 125 x 51 x 128 and it's pretty fast.

We're just looking for DS9 functionality. Not anything more fancy.
Thanks again for this. It's a nice feature.
