Hello,
There is a way, like a shortcut, to reload a file you currently have opened in Photoshop, without the need to open it again and select "update"?
For example, BodyPaint have this nice Revert Texture to Saved which works just fine.
Edit:
Nevermind, I've found a workaround, if you edit the file, like painting something, and then hit F12, it will revert the file to the saved version.
