When using Photoshop on my desktop Mac, I work in "full screen mode with menu bar" most of the time. I have one monitor so I have an image area and tools/palettes areas that share the space. I use command-0 to see the full image a lot, but I run into a situation that could be better I think: maybe you'll agree. When I hit apple-0 to see the full image, the way it works now is that the image fills the size of the monitor. This is good sometimes, but I'd love a preference for that key command to toggle between "fill the monitor" and "fills the available space not occupied by palettes and tools". I'm constantly typing apple-0, then apple-minus to zoom out just a little to make it smaller and then moving the image with the hand tool via the space bar, to the open, non-palette/tool area.
My three steps could be one! 1) Command-0 > 2) Command-minus > 3) Space bar & move to middle ... could be ... 1) Command-0 ... and be done! All with just a preference option.
Thanks for offering a place to make these requests!
