Tensor view should have hover preview for values just like 2D vie

[Wumpf]

Essentially this:

but on the tensor view

Also worth noting that we may want to merge tensor & 2D image view at some point. But this may be longer out.

Any updates on this? This feature would be extremely useful to me. If it is not too much work, can you point me to the relevant part of the code where I could perhaps contribute? (where the existing magnifier glass feature is implemented for images and where to add it to for tensor view)

+1 on @yilun-wu's comment This feature would be a game changer for me. Any pointers appreciated.
