Introduced in Photoshop 23.4, Guide Enhancements provides additional guide functionality at the document level to customize and streamline day-to-day work in Photoshop. Guides enhancements include adding the ability to customize and colorize guides, edit guide properties, access guides via new keyboard shortcuts, and accessible guide options with a new right-click context menu. Users can now also delete guides with the delete key and multi-select to edit and move guides.
We hope you give enhanced guides a try and provide feedback if you run into any problems. Check out our HelpX documentation for more info.
It appears that this update did break snapping to objects and the document itself. In a test I did to see how bad it is, out of 20 different attempts to get a guide to snap to the 0 point on a document, it only did so successfully twice.
This feature totally broke the way guides are supposed to work. Guides arent snapping to the correct place even when using "Snap To" on specific layers. I have to be zoomed way in for it to snap correctly to the exact pixel, which didn't happen on at all two versions ago.
