Hi Nikolai,
First impressions of v2.94 are very good - not only have you included the single FOTS header item that I was after, but you have also created an 'options' panel that allows anyone to include 'any' of the FITS data that they need.
In fact, you have even provided the 'building blocks' for an 'automatic sequential renaming' script that I currently still have to turn outside of PixInsight to be able to achieve. (I use 'Sequentialise' by Polybytes - free - but seemingly no longer available - which is a shame, because it really was excellent at doing its job)
I will play with 2.94 as time allows, and will get back to you (heck, who knows, I might even find time to upgrade PixInsight from 01.06.01.0625 - but that means I need to shut down the copy that has been running for over three months now - and THAT means saving all those hundreds of little PI Process Icons that I have been working with on all those dozens of images, on all those multiple Workspaces. Who says PI is 'unstable'
?)
