I do not use QtPfsGui (or pfstools in general) either, since my
objective is to capture high dynamic range and process it in a way that
the final LDR image looks naturally. That is quite difficult with the
available tone-mapping operators from true HDR.

That's what I am using together with hugin (or auto_align_stack)
already. Is it based on version 4.0, which was released recently?

It would be fine to have

x the possibility to turn off/on some images of the exposure stack and
see the impact on enfused result in real-time (possibly on down-scaled
preview). The same with the weights for contracts/sharpness.

x allow for setting (at least in configuration) of other switches of
enblend (like GPU use, number of levels)

(I have not used your pseudo-HDR editor yet, so if such a possibility
exists already, excuse my ignorance.)
