Developing persona - please make it 360° seam aware

[1drey 5]

HI all,

I often face the need to convert 32bit 360° panoramic image, created with the aid of stitching  software, into tone mapped 16bit image. Affinity Photo does a decent job performing this task, but it always creates the seam, clearly visible when edited panorama is displayed in 360° viewer. It is really disappointing. Yes, there is a workaround  - to duplicate the source panorama, offset it (wrapping around), make identical development, put it as a layer over first development (ofsetted after development) and use respective area from the second development to cover the seam.  But it is time consuming

Same for the tonemap persona. Editing with  it creates even more visible seam and sometimes a tiny, but noticeable 'vortex' around zenith and nadir points.  

I hope it is relatively easy to implement.

That's how the seam looks after the Tonemap persona.
