Add ProPhoto colour space as a "working color space"

I voted yes but stil are confused by the fact we can’t “see” in which color space DxOPL is working.

here is Doquocbao explaining the settings you can do.

The term “Original” means that PhotoLab seeks for this exif field and use this color space.
i suspect in output this is the case.
But in what colorspace you work in the editor when selecting in the export a colorspace?
i hope/ suspect it just works in biggest workspace it can handle (default AdobeRGB?) and is clipping results by export settings as in export to disk and the viewing device settings in preference.

Because if so then a exposure correction/contrastcorrection/colorcorrection can float a color inside your export colorspace (sRGB) and isn’t lost inside DxOPL converter area.
If camera gamut is “clipped” by the selection in export and screen mode then we have a problem:
all data is lost and corrections can’t use data outside the sRGB colorspace if chosen.

This is very unclear by me.
