Hi there,
It would be an useful feature indeed.
In the meantime I started to use the following workaround (i know it's
static and lacks interactivity but it works for me good enough): I do the
thresholding and then I use create selection, which I add to either
RoiManager or to overlay. Then I can reset the LUT and play with the B&C in
order to see how the threshold worked.
