Is a big problem: when moving pages from different Documents with the same options, master pages and Layouts the pages moved are shifted (to the left or to the right).
I've made an Example in the attached Files.
1.png shows the way I move the last two pages of the document to the other document (identical copy of the same file).
2.png shows the pages moved in the second document (they should be the same but the imported ones are shifted by a few millimeters).
For documents where you have to import hundreds of pages it is very frustrating to have to manually rearrange them all.

Version of Adobe InDesign, InCopy or InDesign Server

Adobe InDesign 15.0.1

macOS High Sierra 10.13.6

iMac 27 Zoll End 2012

Steps to reproduce the issues
See also attached video

Open the file > 01ExposeTEMPXMLStart.indd
Generate a merged document by clicking the button
Choose "Honor existing frame fitting" in Content Placement Options
Click [OK]
Jump to page 1 in the merged document
The pictures are placed without honoring the existing frame fitting options from the object style
This only happens with frames that are placed on a master page. The same frame on a document page works fine

Expected result
Data Merge should honor the new feature "Honor existing frame fitting options" on master pages al well

Actual result
The existing frame fitting options even by object style applied is ignored

Workaround
If a object style is already applied you can remove the local override by pressing the "delete local override" button

Steps to reproduce the issues

Open Document "02VKLeerzeilenTEMPEnde.indd"
Open Data-Merge Panel
Generate a merged document with click on the button
Uncheck "Remove Blank Lines for Empty Fields" in Content Placement Options
Press [OK]
Repeat Step 3 this time Check "Remove Blank Lines for Empty Fields" in Content Placement Options
Press [OK]
Put the documents side by side
Activate "Show Style override" in the paragraph panel
Jump to page 2
On the left side (Merged Document, Blank line intact) you can see the 2 markers followed by a paragraph symbol
On the right side (Merged Document, Blank line removed) you can see that the 2 markers with paragraph symbol moved 1 line up behind the 7 and the other paragraph symbol is deleted
Everything is o.k. because the paragraph style (07padresse) of the line "Mobile" and the deleted "Blank line" are the same
Jump to page 3
On the left side you can see the 2 markers followed by a paragraph symbol
On the right side (Merged Document, Blank line removed) you can see that the 2 markers with paragraph symbol moved 1 line up and the other paragraph symbol (blue highlighted on the left side) is deleted BUT this time the paragraph style of these 2 paragraph are NOT the same! The result is a bigger gap between the two sentence "Frau Marie…" and Tel: 012…" on the right then it should be as you can see on the left

Expected result
The Blank line (2 markers and paragraph symbol) should be deleted/removed

Actual result
Instead of the Blank line (2 markers and paragraph symbol) the paragraph symbol before that (blue highlighted on the left side) is removed AND the remaining paragraph also picks up the paragraph style from the "Blank line" (if there were text in my example you could see that as well)

Workaround
You can generate a merged document with Blank lines and delete/remove them with Find/Change
Find > (markers) + paragraph symbol = <FEFF><FEFF>^p
Change > to nothing
This way everything stays intact!

This user is much unhappy that inDesign 2020 no longer provides the zoom view box that appeared in the top menu bar, directly to the right of the help tab. That was a fast, easy way to change the view size of the file in the screen.

I was told by Adobe that this feature was dropped because the screen size view could be achieved by other existing features. Sure... now one must pull down a tab, then go to another command and activate a feature like zoom in and zoom out. And that only shifts the view in or out by one factor, whereas the zoom view box at the top menu bar would let you instantly jump the view in our out by 3 or 4 "sizes."Count me as a most unhappy user who will stay with inDesign 2109.

By the way... inDesign 2020's menu bar is now empty to the right of "help." So what was gained taking this highly useful feature away? And why not give users the option to have that zoom view menu feature in one of the pre-sets like "Essentials Classics"? I will grumble once more about my unhappiness at the loss of this important feature and the hubris of Adobe engineers to drop such a valuable element of this software.
