Without snapping, measuring between points is not very accurate.
It would be nice to be able to measure actual lengths of curves or sections of paths. It would make it easier to create diagrams with dimensions.

FREE FORM GRADIENT - The new feature in Ai CC 2019. You can create amazing gradients, however, you cannot save any free form gradient created to the swatch panel or the Cloud Library....why ?

Its a great feature, however, it makes for so much extra work if you want to use any free form gradient you create in one file, in another file or project in the future....it would be logical to be able to save this new style of creating gradients to the CC Library and to one's Swatch Panel.

I would like to be able to rearrange (customize) the features in the new 2018 properties panel. I want to be able to add, remove and rearrange the features in the panel. This way the panel will only shows what I want it to show and get ride for the stuff I don't use. I would like to at least be able to collapse what I don't use.

Give users more flexibility with the program interface please. This will help alot of people with eye strain.

If you have multiple objects selected that range in size, say .5" to .75". they ability to select them all, then size them ALL to 2" and not just the first object to hit 2".

Don't tell me abous mesh trick, it has it's limits and surely is not that easy to use.
Just make Conical type gradient from the box.

Since Free distort doesn't support images at all, both linked or embedded.
I have to use envelope distortion each time I need to distort an image within AI.
But I have to break link with image for this, because Envelope works only with embedded images sadly.

I have a Chromebook and I have a need to make logos. We need Illustrator!

There should be a way to organize all symbols (i often use more then 30 symbols per document), it gets very messy in the symbol window. It would be so much easier to organize and keep track of everything with the ability to create folders in the symbol window.

like if we could group layers in Photoshop and name it will be super.

The bounding box is non-existent for graphs drawn in illustrator. Have tried turning on/off "hide edges" under view, restarting, shutting down, but nothing is working. Scaling tool is useless too as the bounding box remains invisible.

InDesign gives you the ability to generate a vector QR code on the fly, I was unable to find a way to do this in Illustrator and would love to have this option if possible. I design a lot of packaging art that will sometimes require a QR code. This way, I can generate a QR code that is a high quality vector without having to import one from another source. Thanks!

Punctuation marks justified alignment on textbox.

Need to automate the text alignment in the textbox for Chinese characters.

Because it is very time consuming to do manual kerning for each characters reiteratively, whenever there is amendment to the text in the box.

Some text editing shortcuts would be very welcome:
Ctrl + End: go to the end of the text
Ctrl + Home: go to the beginning of the text
Ctrl + Delete: delete all characters of a word to right
Ctrl + Backspace: delete all characters of the word to left

Accessibility is incredibly important. Obviously Adobe wants to help but it is incredibly limited in Illustrator. If you supply multiple artboards, character and paragraph styles and great text placement options, you should make the PDF export carry those options through. What's the point of using InDesign when you only have two pages? Who needs to files for every project?

When you pan with the mouse button/wheel held down, the panning stops when the cursor reaches the monitor edges. This forces user to release mouse, move it all the way back and re-grab it.
In some other editors you can continue to move the pointer and it will 'wrap' around your monitor, going from the opposite side of it, until released.

Basically you can pan until you reach the end of your table.

This mode will help those who have to work at scale and pan without unzooming. Please, add it!

Illustrator CC 2019 and InDesign CC 2019 generate "Typequest" caches in separate folders by Visual Font Browsing, but occupy the disk because each cache size is large. 
For Japanese, the font data becomes very large.
In the future, it is not practical to generate caches individually for other applications, so caches should be shared by applications.

(Translated to Japanese)
Illustrator CC 2019 と InDesign CC 2019 は、ビジュアルフォント表示の ”Typequest" キャッシュを個別に作成しますが、このキャッシュサイズがとても大きく、ディスクを圧迫します。
日本語の場合、フォントデータがとても大きくなります。
今後、このキャッシュを Adobe アプリ全体で共通利用させ、個別に作成しないようにしてほしい。
