The main window of the Photoshop Replace application offers many features for customizing and optimizing the workspace.

Here are some basic operations that can be performed:

1. View control using the slider: The slider is used to view long file names without reducing the workspace size, allowing the entire name to be seen by sliding.

2. Changing the size: This feature allows users to adjust the workspace size by dragging an orange line, enabling enlargement or reduction as needed

3. View Tab Choosing: Right-clicking provides the option to enable or disable specific windows in the application, including choices like Attribute View, Replacer Editor, and Version Control.

4. Detaching the tab: This option allows for detaching a tab and positioning it in a convenient location as per user preference.

5. Changing the size of the Attribute view tab: Modifying the size of the attribute view tab allows for better tailoring of displayed information to user needs.

6. Closing tabs: Each tab in Photoshop Replace has a function that allows it to be closed.
