P: Can't create ruler guides while transforming a layer

I can't believe Adobe would call dragging a ruler out easily a 'legacy'. This has to be a bug, and not an intended feature.

Plus the auto commit when transforming is a major slow down. Any stray click and the wrong transform is committed. I've gone back to 2018 version for now.

Legacy functions would be wonderful!

This update of PS has been a major bungle for long-time users. The inability to bring out a guide from the ruler while transforming is a core-basic function (IMO). A simple option to re-enable legacy functions such as this would be greatly appreciated. 

My fingers are going to get all tangled up trying to add and subtract modifiers as I do all this. I'd rather a preference, a toggle on the Options bar, something besides changing up all my modifiers. How much easier have we just made it by changing behavior in the first place, rather than making giving us all options?

But thank you for the Cmd key to prevent click to commit. It works with type, too, which has been the bane of my existence—before they added Transform to the mix.<G> I might get used to it because I'll be using it ALL the time now.

cmd/ctrl works too for non-commit... super-intuitive!

You can already hold the cmd/ctrl down when transforming to bypass the click to commit mess... no change needed. What used to be an intuitive transform process is now incredibly frustrating, with hidden keyboard toggles which prevent time loss.

they tried to make transform and commit easier for beginners to understand and then simultaneously made both behaviors more difficult for everyone to use.

sounds like a 'fix' is in the works and hopefully they'll get it right this time so that we can get back to work.

Same problem whilst transforming here, trying to drag out a guide will commit the transform.

Pressing shift when dragging out the guide does allow to do drag out a guide, but Shift needs to be released after dragging so the guide doesn't move in stepwise fashion.

Also, clicking outside the transformed bounding box will often commit the transform, this is annoying when trying to grab corner handles, and clicking just outside etc. This didn't use to be the case.

The same thing happens with Crop tool, in Classic mode. I like to add guides as reference using crop tool (as opposed to comitting the crop). This can't be done anymore.

I hope we can get the previous transform / guides functionality back as this is a downgrade in functionality.

I'm using 20.0.2.

You now have to hold Command key when you drag a guide from your ruler while in Transform mode.

Holding the Shift key while transforming also works when you're trying to stretch the image in only one direction.
