Perhaps check spam folders, I regularly find some mails from this list there 
(not sure why, perhaps too many urls/phone numbers?)

I am not receiving all emails, just some. I didn't receive any that gave
information about the preset, only emails that indicated there was one.
Would someone fill me in?

Hi Kofa,
  I installed your preset and watched the video link. I believe I have
improved upon your preset a little. In the YO curve you have dropped every
level down to noisy. If for the finest detail (far right) you lift this
half way you reduce luma noise without losing any significant level of
detail. BTW, when I really experimented with the UOVO curve I independently
decided on an identical setting to yours. I have tested my preset on a
number of challenging presets and it works so so so good.   Thanks for this
guidance. BTW, is there any way to change the default option for this
module to my new preset?

Hi,



If I first select auto-cropping, no matter which one and then get structure
and correct, it produces the black stripes / strange crop. If I first do get
structure and correct and then choose auto-cropping it behaves OK.  Both
with lens - specific. If you meant that.

No, in my case it makes no difference.
On the other hand, it would seem that if you activate the module searching
and correcting, and then later select the automatic cropping in the original
format, the module behaves correctly and does not create problems, have you
tried?

Good morning,
I am writing to report that I am having difficulty using the "perspective 
correction" tool.
I usually select the following:
Guides - deactivated
Auto crop - original size
Lens model - specific

click on Analyze ...
click on Correct ...

Initially the module works correctly, identifies corrects and cuts in the 
manner indicated.
As soon as I select a new image from the previews below, the newly corrected
image loses the "auto crop to original size" and the black side portions are
highlighted.
This happened to me with all 3.x.x versions
With the 2.x.x versions of DarkTable this never happened to me.
The method I use is always the same.
Because?
