As per the title, when working with a CMYK document with 100K blacks, when exporting to RGB, these should always get translated to RGB 0,0,0 - regardless of what Printing/Exporting setting is used in the Appearance of Black preference menu.

Right now, when exporting a CMYK document to RGB (regardless of whether you use PDF, PNG or JPG), if your Appearance to Black Print/Export setting is set to "Output All Blacks Accurately", you will end up with incorrect black levels. What really should be RGB 0,0,0 ends up being RGB 35,31,32 or so. This is true even when working with 1-bit bitmaps (which are nothing but pure black & white).

This can be fixed by changing Appearance of Black - Print/Export to "Output All Blacks as Rich Black" - blacks end up being proper RGB 0,0,0 black - but it really should work like this regardless of what the Appearance of Black settings are set at.

A couple samples:
"Accurate" blacks PNG: https://my.mixtape.moe/metyyt.png
Rich blacks PNG: https://my.mixtape.moe/bpgnib.png
"Accurate" blacks PDF: https://my.mixtape.moe/qjqcfv.pdf
Rich blacks PDF: https://my.mixtape.moe/rrhaig.pdf

Again, the "accurate" black exports should really look the same as the rich black exports by default - black should be proper RGB 0,0,0 black, instead of somewhere around ~32,32,32.

Please consider the addition of a dynamic unit of measurement that relates to the document’s baseline. Such a unit will make it possible to express various parameters throughout the design as a multiplication or division of the document’s baseline.

We would for example be able to express a header’s leading as twice the number of baselines, or a paragraph’s space after in any number of baselines.

The unit’s relation to the document‘s baseline means that it’s dynamic: whenever you change the baseline, all values expressed in this unit will change accordingly. There will be no more need to adjust these parameters manually.

I tried to write this response in the "Help Improve Adobe Products" window that opens up on launch of Indesign, but I ran out of space:

Indesign has layer after layer after layer of instructions on how do even the most common things. The problem is that in order to understand one layer, you have to understand at least the terminology and concepts of the other layers. These days, when you open the box for many devices there is a quick set up document included. I recommend that you do something like that. But not with instructional videos. Someitimes you have to watch a video several times to learn a task you make only need to use once. Furthermore, the instructors sometimes use terms that are not known to the viewer. Sometimes their mouse moves too rapidly to follow.

Here's what I suggest. Configure a very simple numbered sequence for a given task. Make it such that the viewer can do what he needs and then move on, ie without requiring a full education in all the capabilities of the task.

I suggest you let me send you an example of what I'm speaking of. Perhaps an example of how to change the color of text without having to master the use of swatches.

Please let me know if this interests you.

Great and awesome product! But it's like learning to drive an aircraft carrier!

At present, a cross reference takes its case from the destination. If I have used small caps for the destination style, but am referencing it from within text, I want to capitalise the term, but the cross reference takes its case from the destination, not the typed text.

To get what I want I have to cause a problem for the cross reference (yellow triangle with exclamation mark) and manually fix the capital start letter, or use hyperlinks and text anchor – a two-step action making a destination and hypherlink that cross referencing was supposed to fix.

It would save a lot of time if either the case used for the x-ref text was used as the default, or we could specify a case for the start letter of an x-ref.

Searched InDesign support for "pagemaker file conversion"
The top article (dated March 2017) is titled "Convert QuarkXPress and PageMaker documents to InDesign". Here's the address of this page: https://helpx.adobe.com/indesign/using/converting-quarkxpress-pagemaker-documents.html This article is part of the "InDesign CC User Guide." In the right hand column, it says it applies to InDesign CC. The first sentence in the Pagemaker section is "InDesign can convert document and template files from Adobe PageMaker 6.0 and later." It proceeds to give directions. I have come to find out that these instructions cannot be followed in InDesign CC, but only in InDesign CS6. This resulted in me wasting about an hour talking to Adobe's truly worthless support representatives.
This webpage needs to be corrected. Just replace that first sentence with: "InDesign CC cannot open or convert PageMaker files, but there is a solution. Start by downloading and installing InDesign CS6. Use CS6 to open and convert your PageMaker files (instructions below). After you save them as InDesign documents, you will be able to open them in InDesign CC."
It is clearly in Adobe's interest to help their customers avoid contact with the Adobe support staff. Correcting this webpage will be a move in that direction.
