Most people typically use a subset of the many panels that Photoshop has to offer at any given time. For example, if you are color correcting an image, then you may want the Info, Histogram and Layers panels showing but if you are recording actions to help automate tasks, you might want the Actions, History and Layers panels open. The easiest way to switch between the sets of panels that you might need for different tasks is to save them as Workspaces.
To create your own custom Workspace, rearrange the panels that works best for your workflow, and use the Workspace Picker (on the right of the Options bar) to choose New Workspace. Give it a name, and save the Workspace. (Workspaces can also be saved via Window > Workspace > Save Workspace.) Your workspace (as well as the default workspaces that ship with Photoshop) will appear at the top of the list in the Workspace Picker.

FYWIW -Just because Photoshop ships with the Toolbar on the left and the Panels on the right of the display, it doesn’t mean that they have to stay that way! When working at home, I prefer to dock my panels to the Toolbar on the left side of the screen. This saves a significant time over the course of the day by eliminating the need to travel back and forth across my monitor to select different panel options, tools, and tool options. (see screenshot below). Notice that I have also placed the Properties panel below the Layers panel so that when I add an adjustment layer, my cursor is automatically above the options for that layer.
Foe added flexibility, Workspaces can also contain custom Keyboard Shortcuts and Menu items. And, when using more than one monitor, you can distribute Photoshop’s panels to multiple monitors and save them as workspaces.
