The options in the Window Menu vary depending on whether Photo Mechanic is running on macOS or Windows.
For example, newer versions of macOS support window tiling, positioning, and sizing options that appear in the Window menu that are not available in older versions.
The options that remain constant that come from Photo Mechanic itself are:
Select Next Tab: Switches to the Contact Sheet tab to the right of the current tab.
Select Previous Tab: Switches to the Contact Sheet tab to the left of the current tab.
Ingest Tasks: Opens the Ingest Tasks window.
