Newbie questions for MoveAnything

I just started experimenting with MoveAnything for the first time. Maybe some more experienced users can help me with the following questions I could not solve in spite of extensive trial and online research.

What is the meaning of "synchronizing" in "synchronizes all frames modified by MoveAnything"?
I cannot notice any effect when clicking the "S" button and the documentation does not say more than this sentence...
What is the purpose of the option to "synchronize frames when exiting combat"?

What is the purpose of putting frames together in groups?
Just that you can move them together retaining the relative positioning among them?

Is it possible to emulate the original UI, such that one frame (e.g. MerchantFrame) changes its position when another frame (e.g. CharacterFrame) opens?
I tried setting the MerchantFrame (TOPLEFT) relative to the CharacterFrame (TOPRIGHT). But the MerchantFrame does not seem to take into account whether the CharacterFrame is open or not.

Thanks!

I still don't know the answers to my first two questions, but I figured out a way to emulate the window repositioning I was referring to in the third question. If anyone is interested in this, add the following code to the end of MoveAnything.lua:

Code:

-- Function to check if the CharacterFrame should push away another frame.

function MovAny.characterFrameCheck(f, ...)

  

  -- Check which frame is open to replace the CharacterFrame, if any.

  local frameToMove = nil



  -- Only one of the following frames can be visible at a time!

  if (MerchantFrame:IsVisible()) then

    frameToMove = MerchantFrame

  elseif (MailFrame:IsVisible()) then

    frameToMove = MailFrame

  end

  

  if (not frameToMove) then

    return

  end



  local opt = MovAny:GetUserData(frameToMove:GetName())



  -- Check if CharacterFrame is visible.

  if (CharacterFrame:IsVisible()) then

    opt.pos = {"TOPLEFT", "CharacterFrame", "TOPRIGHT", 20, 0}

  else

    opt.pos = {"TOPLEFT", "CharacterFrame", "TOPLEFT", 0, 0}

  end

  

  MovAny.Position:Apply(opt, frameToMove)

  

end



hooksecurefunc(CharacterFrame, "Show", MovAny.characterFrameCheck)

hooksecurefunc(CharacterFrame, "Hide", MovAny.characterFrameCheck)



hooksecurefunc(MerchantFrame, "Show", MovAny.characterFrameCheck)

hooksecurefunc(MailFrame, "Show", MovAny.characterFrameCheck)
