This request is obviously a little too late for 15.3 but hopefully this is doable for the next version!
This has always been an annoying thing for me with the Field calculation dialog pictured.
When you want to change the context of the calculation (which is often when working with an Interface table), you change it via the drop-down at the top. The problem is that the current table occurrence on the left does not change. You always have to change this context to be the same as the one you just chose at the top and this is super frustrating.
Is there any way possible that these two can basically be in sync so that when the top context changes, the 'current table' automatically changes to be the same one? There really is no reason for these two to ever be different upon changing of the evaluation context.
I would be eternally grateful!
