No, it is not that same thing: I have already turned it on and it just saves all the frames that are used in enhancing (aka livestacking), while I want is to save ALL the frames, including those discarded by enhancing, because often many of those discarded by enhancing are still usable in an offline stacking software, like DSS, Siril, Astro Pixel Processor, PixInsight, etc.
When that option was available as an "Experimental Feature" I noticed that in, say, an hour, I could get something like 300 useful 10 seconds frames instead of 200-240 with enhancing.
