When I render a new panorama and save the picture then the customized target filename format is used with e.g.
I miss here a new variable (e.g. %p) for the used projection.
This is extremely useful when comparing different variants.
Even more when I use "automatic" I would appreciate even some days later which projection (e.g. "hammer") was used for rendering.
Could authors introduce this tiny littly new var?
I think it is easy to implement.
Isn't this what you seek?:
