Feature request for non destructive flip canvas

It is already 2018 and yet adobe has failed to implement flipping canvas horizontally. We artists use hundreds of layers and the file dimensions can be as high as 4k-8k pixels. Photoshop's incompetent flipping tool takes 10 years to flip that kind of working file while other software like SAI and Clip Studio can do that in 0.3 sec. Everyone knows that artists require constant flipping of canvas to check for distortions. What makes it worse is that if you undo after flipping, the dumb software will flip the view back??? Even SAI and Clip Studio ain't as dumb as that. What's your excuse adobe? People pay a premium for your software yet you guys lack basic tools.

In case you guys are curious about the specs, I use i9, gtx 1080, 64gb RAM and multiple SSDs so don't even think about questioning my hardware.
