The MacOS Finder window is highly customizable and can be easily updated to fit your needs. For example, if you have a folder you access regularly, you can add it to the Finder sidebar for quick access. Just navigate to the folder, then click and drag it over to the sidebar. For apps, hold the Command key, then click and drag the icon over. You can remove items by doing a mouse right-click > Remove from Sidebar or by going to Finder > Preferences > Sidebar.
