Create tables by anyway, it shouldn't have much options, such a simple table (simple borders), instead i have to draw lines to get a view of table.

Have an option for the text to adjust to the size of the text box for longer text for variable input purposes.

Starting with v24.3, vertical text alignment is now available. This is a great feature we have been waiting for. However, characters in Japanese fonts are misaligned at the center and bottom, as shown in Figure-1.

This is probably due to the fact that the bottom edge of the character is used as the baseline.Maybe we need The Last Baseline option.It's a tough road. But the Illustrator team can make it happen, I am sure of it.

Japanese:
v24.3より、垂直方向のテキスト配置が利用できるようになりました。これは待ち望んでいた素晴らしい機能です。しかし、日本語フォントの文字は、Figure-1に示すように、中央揃えと下揃えの位置がずれてしまいます。
これは、文字の下端をベースラインとしていることが原因と思われます。末尾ベースラインオプションが必要かもしれません。大変な道のりです。しかし、Illustratorチームはそれを実現できる、私はそう確信しています。

Why do we have to go through the complicated hassle of making custom document profiles to change the default font to something other than Myriad?

The "TateChuYoko" using for vertical writing text, under use in Japanese environment.
The adjustment value is set only to integers of points and it is very troubling.
In that state, I can only do a rough job too much.
I would like to improve so that more detailed values can be set.

<Japanese>
縦中横設定の調整量がポイントの整数値ごとにしか設定できない。
これでは大雑把な仕事しかできない。
細かい値を設定できるよう改善して欲しい。

AI ignores NBSP when it's places as symbol. 'No break' option is an option but ridiculously hard to be applied quickly. Anyway NBSP should work

macOS10.15、11
Illustrator 25.4.3

１．ドキュメント上にテキストを入力し、フォントを指定するために文字パネルを開きフォント名をドロップダウンする。
２．フォントプレビューを非表示にした場合、モリサワフォント等接頭辞の大きなフォント（特にAP-OTFで始まるもの）は不適切な省略表記となりフォント名の特定が困難となる。

これはフォントの命名にも絡む問題で一概にIllustratorに問題があるとは言い難いものです。ですから、ドロップダウンをプレスした際に表示される幅を可変にして略記表示が問題ある場合にユーザーが表示幅を調整して認識できるようにしていだだけたらと思います。

添付画像の矢印部分をユーザーが調整してフォント名の表示部分の幅を任意に調節することで略記の部分を変更できるようにしていただけたらフォントを探す際に楽になるかと思います。

I always get annoyed that my font drop down menu always starts at the top in the most recent section.

can i get it to stay at the location where I last opened it/font I last selected?

Please add paragraph rules, like InDesign. This would make creating nutrition facts on package designs much easier than having to manually draw them.

Please add support for Hunspell dictionaries in Illustrator. Users from countries which languages aren't supported feel discriminated, because we pay the same price for the software as the others.

Would love for the ability to copy formatted text directly from within Illustrator and paste into InDesign without it removing the formatting/styles.

Valerii Mamedov pointed out the problem with side bearings, when each new line of text is shifted from the edge:

This forces us to manually kern first glyph, which takes time, changes upon new font and still lacks precision.

Besides other appliances Illustrator is used for typographic design, and if user could set trimming of side bearings as a paragraph option, this could greatly help with font visual alignments.

The problem is amply described here:

例えば、「第1章」という文字列に対して、数字だけを大きくしたとします。
この際に和欧文間隔は当然適用されるのですが、その（アキの）基準が数字の前後で異なってしまいます。
添付画像をご覧になれば一目瞭然ですが…数字の前は数字の文字サイズを基準にしており、数字の後は後続の文字が基準になっています。
普通のアルファベットの場合は、前後とも直前と直後の文字が基準になっているのは画像の右でお判りいただけるでしょう。
これはずーーーーっと改善されておりませんので、是非ともアルファベット同様な挙動になるように改善をお願いいたします。

Currently, OpenType features settings can only be set in the OpenType panel. As a result, the user experience is poor. Being able to set OpenType features in the Character panel will improve the user experience.

We have Favorites in Font Family drop-down list, but that's not enough. Allow us to create our own custom filters / tags and manage them.

In Adobe Spark, when creating a Post, there's a nice feature which allows you to create a dynamic text box which capitalises, scales, and fits the words to a text box, as you click and drag the handles of the text box. In Adobe Spark the feature is called "Capitalize & Fit". It would be nice to have something similar in Illustrator.

We need to extend Type on Path to allow it to be multiline.
The picture does explain it well enough.
Instead of manual offsetting lines (I used AG Offset tool to make a lot of them at once) and making threads, we should be able to just tick an option and get a LIVE result.

Also, please see the related request about upgrading the UX of Type on Path as well:

Provide for nested Character and Paragraph Styles in Illustrator. This is a staple in InDesign and would be very helpful in Illustrator. We have standardized on Illustrator for many templates in our workflow. In general, Illustrator is more appropriate, but text editing is a weak spot. This would help.
