P: Doesn't constrain proportions when resizing from side handle while holding Shift key

Agreed. Now people have to remember which Adobe program does it one way, and which Adobe program does it the opposite way. Exactly like I have to remember that in Photoshop, a positive number rotates an object clockwise, but in Illustrator and InDesign, a positive number rotates counterclockwise. It took 24 years to address the issue, and they did it wrong. MAKE IT WORK LIKE ILLUSTRATOR.

Why was a feature that has become as common as copy or paste been changed so that hokdingbthe shift key does the exact opposite of constraining an image, this recent upgrade shift allows for distorting not constraining, constraining is setvas a default now. A smart move, 20+ years ago. A dumb move now.

Hi Kris and Roman,

As of today's update, Photoshop 20.0, proportional transform is now the default behavior of transform in Photoshop (except with regard to vector graphics). Please open the Creative Cloud app, download the update and let us know how it goes for. If you do not see the update immediately, please sign in and sign out of the Creative Cloud.

Thank you,

Hi,
uniform scaling when dragging middle handle + shift would be really awesome.

Doesn't matter. This applies to every version, up to the very latest. This should have been fixed a decade ago.

Which version of Photoshop are you using?
