I normally work with a Macbook connected to a 23" Cine display. Pulled the Macbook off the display, opened Photoshop, and the bottom of all the action panels (actions, layers, channels, etc...) are below the lower edge of the screen and there appears to be no way to recover them.
The program is essentially useless until I can get connected to a big display, simply to click on the bottom of these panels.
What's the secret to resizing these?
Just found that reseting the workspace to "essentials" is an effective workaround.
Not perfect, as simply having the option to make the panel fit to screen or resize would be optimum, however resetting means I can at least start from scratch re-arranging all the panels.
You could rearrange everything for best use on the small display, and save your own named workspace (e.g., MB Small) and arrange everything for best use on the large display and save that as a different named workspace. Then it won't be too hard to select one or the other.
Curious where/what that display prefs option is. There's some fundamental difference between "windows" and "panes" in Photoshop that causes one to resize & not the other.
In PS window > arrange > match zoom will fit all the image file windows proper, but doesn't affect the various tool panel arrangements & sizes. Resetting the workspace at least gets the user back to square one.
Saving different workspaces for each monitor as suggested above might work great as well - would be fantastic if there was simply a way to resize a tool pane that's wandered outside the boundaries of the display...
