The new stacking feature is great, but could be even greater

The new Stacking feature is something I have been waiting for a long time. Still I would like to see a few additions:

  1. It would be efficient to be able to set the stacking mode in the Settings, so that a folder show stacking without interference.
  2. Although I can stack an original file with all developed version by setting the time difference to zero, I would like to have the option to select stacking by file extension.
  3. I prefer to see the developed file on top of the original (raw) file, but when opening a file from a stack for further customising I prefer the original and not the file on top of the stack, as it is now

100% agree.
This is basically duplicate & extension of this feature request created a couple weeks ago: Better manage RAW+JPEG pairs using stacks - #3 by Wolfgang

If I were you @LarsN I would add your comments to that one and upvote it, and then close this one. Disparate posts about the same thing will be less effectual then all communication and votes into one.
