For about 14/15 years I never had to reset preferences in InDesign.

Since CC2017 it's more or less once a week.
Colors disappearing.. panels blind or empty.. tools not working.. font now showing.
Panels self increasing size...

But it seems we have to deal with it, so we probably need a way to SAVE PREFERENCES.
**Save preferences in a moment everything work fine.. and restore it when (after just few days) nothing works anymore.**

Every time people have to reset preferences, they have to restore everything. UI colors, workspace, Application Frame (that mac users normally never use) Old Dialog way (the new are unusable and way too slow).

Too many things to restore and too often.

We need “Wavy line” customize option, such as:
(1) weight (2) wave height (3) wavelength (4) single/double line selection
(see fig1.png and fig2.png)

Current wavy line design is not good for professional.
When we change weight, the wavy size is automatically changed. We can’t control the size of wave.
When we need to control the size and shape of wavy line, we have to create appropriate one by Illustrator, then link them. This takes lots of times of us.
"Wavy line" customize option will definitely help us a lot.
Japanese clients often designate to use wavy lines to underline.
With current feature, we can not customize wavy lines.
To make clients satisfy, we are always struggling against wavy lines!

タイトル：波線のカスタマイズ機能を追加（太さ／波の高さ・幅・／一重・二重線）

内容：
現在の波線機能は、線の太さを変更すると、自動的に波の形状が変わってしまい、
思い通りの波線にするには、イラストレーターなどで作成し、リンクするなど、
とても面倒な作業が必要になり、時間も手間もかかります。
日本では下線に波線を使うことが多いため、「波線カスタマイズ機能」が追加されれば、とても便利になり、時間の節約にもなります。

Adobe, please change the standard color presets for printing to the proper standard printing conditions and profiles that are published by the European Color Initaitive ECI (eci.org.). The icc-profiles are publically available.
Actually, Adobe still uses outdated FOGRA39 characterization data by default, second Adobe applies FOGRA39 in an own icc-profile that differs from the standard-profile by the ECI.
FOGRA39 is outdated, it's been replaced by FOGRA51 since years, for good reason. ECI has published the corresponding standard ICC-profile "PSO coated v3", which should find it's way into Adobe's color settings. Please integrate the official ECI-profiles, because these are highly optimized by professionals for printing and color.

For example, if a heading paragraph style is Palatino Bold, color value: C15/M2/Y0/K36, 15 point type on 19 point leading, left aligned with an indent of 1p and space after of 2.6p, plus a nested character style, I would all like this information called out in a small label, on it's own layer in the file.

This action would make the same kind of label on its own layer for ALL the fonts styles in the file. This way I can make sample pages of my file and hand them over to someone else to finish up, with an easy guide for how it should be styled.

The links panel should support Groups and Smart Groups. Large numbers of links in projects -- especially those that include a lot of InCopy assignments -- get unwieldy.

Ideally you would be able to make groups and manually move links into them, and also create smart groups that would automatically update. Ideas for common filters that smart groups would be used for:

All CMKY images, all non-CMYK images, all InCopy links, all links that need to be updated, all links that are embedded or not, all links that are currently on a Hidden Layer or hidden via conditional text, etc.

Also, just having a simple text box that can be typed into and have the visible Links narrowed down according to that search would be a big help -- similar to the way the Quick Apply interface works as you type.

Please give us back the former option of layout adjustment (see screen capture) !!
It was so simple and so easy to change page format and objects adjusted well !
For exemple when doing a book cover :
before, you could change the page width of the spine, and if there was a colored frame on it, its width would adjust too (but not the height if the height of the page didn't change)
Now, if you change the page width, the object is scaled (height and width) wich is absolutely counter productive : now you must manually rescale and place again correctly the object...
Why did you remove a function that was so useful and worked well ????

Since CC2019 the user is able to add footnotes inside a table. Such notes are added at the bottom, of the textbox. This behavior does not fit to many needs of designer how need real table footnotes.

So what is the difference?
Real table footnotes stick to the content of the table.
In this case the note gives some additional information to the table specific content.
Therefore each table should have an own mechanism of numbering that does not mix up with the document footnotes numbering. Additionally the position of table footnotes is most often at the end of the table.

This usecase for table footnote is more often used by me an other InDesign users, then the implemented way.
Attached one example.

Hope we see this feature soon, Klaas
