「中央に整列」を実行したときに、座標の平均ではなく選択範囲の中央に揃えたい ／ Align to center of selection instead of average of coordinates when "Align Center" is executed
現在のIllustratorデスクトップ版で「選択範囲に整列」を設定し、複数のオブジェクトを対象に「垂直方向中央に整列」または「水平方向中央に整列」を実行すると、それぞれのオブジェクトの中央の座標を平均した位置で揃います。
一方で、Illustrator iPad版で同じ操作を行うと異なる結果になります。iPad版の「中央に整列」では、座標の平均ではなく、選択範囲（バウンディングボックス）の中央でオブジェクトが揃うしくみです。
自分が確認した限りではPhotoshopやInDesignもこちらの仕様です。
- 「選択範囲に整列」というオプションの名称からも、座標の平均で揃うことは推測しにくい
- iPad版のように、選択範囲の中央に揃うほうが直感的でイメージしやすい
- デスクトップ版とiPad版の同じ機能がそれぞれ違う動きをするのは避けるべき
- 選択範囲の中央に揃う仕様はその他のAdobe製品でも採用されている
上記の理由から、Illustratorデスクトップ版でも「中央に整列」では選択範囲の中央に揃える仕様に変更してほしいです。

In Illustrator on desktop, select multiple objects, and in the "Align to Selection" setting, execute "Vertical ( or Horizontal ) Align Center".
The objects will then be aligned at the average of their respective center coordinates.
However, the same operation in Illustrator on iPad produces a different result. The iPad's "Align Center" aligns the object at the center of the selection (bounding box), rather than at the average of the coordinates.
As far as I have confirmed, Photoshop and InDesign also have this specification.
- It is difficult to infer from the name of the "Align to Selection" option that it will be aligned with the average of the coordinates.
- It is more intuitive and easier to imagine the result if it is aligned to the center of the selection, as in the iPad version.
- It is not good to have the same functionality on desktop and on iPad, but with different results on each.
- Alignment to the center of the selection is also used in other Adobe products.
For the above reasons, I would like the Illustrator desktop version to change the specification to align to the center of the selection.

IllustKit plugin suite by Totallypic now offers two dedicated commands to align objects to the center of the shared bounding box of the selection, the same way Ps, InD, Ai for iPad do.
Take a look at it here — https://totallypic.com/illustKit
It offers more that this, the plugin’s main area is empowering native calligraphic brushes, but it also offers different auxiliary tools Ai forgot to have. -

現在は、分布を行うオブジェクト全体での最大サイズに寄与するオブジェクトが分布範囲の基準となる。
本来は左中右の各分布を行う際、全オブジェクトの各左中右座標のみを基準として評価されるべきと思う。
Indesignにおける分布の挙動が正しい。 -

In InDesign, Horiztonal/Vertical Align Center aligns selections to the center point between the outside edges of a selection group. Whereas in Illustrator, Horizontal/Vertical Align Center seems to average the center points of the selection group. Having used both, it seems like the InDesign functionality is more intuitive: Position the widest/tallest object where you want it to be, then align everything else to it.
Maybe it's just me, but I've never needed/wanted Illustrator to align a bunch of selections to their average center point. Furthermore, getting everything in a selection to have the correct average center point seems like more work than aligning all of the object manually.
Perhaps the Illustrator alignment tools are meant to be a 2-step process: (1) align selections on center then (2) move them to where you want them. That being said, the Horizontal/Vertical Align Center seem to be the only 2 buttons that use the center points of selected object rather than the outside edges.

I agree. Guess where these objects will be centered? The answer in the attached video.

This "average of coordinates" is an archaic Illustrator specification that remains. There is no reason to use this specification nowadays.
この「座標の平均」は、古めかしいIllustratorの仕様として残っているものです。今となってはこの仕様を使う理由はありません。
