P: Ability to flip individual Artboard without flipping the whole canvas

To put it in a simpler way-

Currently, artboards seem to be programed as margins of a single bigger canvas, each with some layer controls individually.

In future updates, I am looking forward to seeing each artboard as an individual canvas of its own, with full controls of flipping, rotating as well as layer controls and so on. Thus working with artboards becomes more like standing in front of a magical whiteboard.

THANK YOU SO MUCH, MR. STEPHEN!

This will be very helpful for a while until Adobe adds or changes its Flip feature
I'll comfortably use this for a while, thanks! 

This is insanely cool!

You can try the following script. Select the artboard and run the script. A new preview layer will be added at the top of the artboard stack. You can then toggle the visibility of this layer on/off to preview the flipped image. Then delete the layer once you have finished previewing.

This has had limited testing, so I might have missed something!

This topic is marked as an idea, this is the way to submit a feature request to the developers.

Thank you, is there any way to ask for or a way to provide ideas to Adobe?

At this point, the only option is for an end-user to create a solution and you wait for Adobe to implement such a native feature.

so as for now there's no solution or maybe from adobe to improve the artboard?

That's OK, I'll knock something together.

im sorry i dont understand on how to work on that

I don't have any control over what Adobe may or may not add to future versions of Photoshop. If you require this now, then an action or script can be used as a workaround.
