You can add up to 3 links in your proofing events menu bar. From the proofing control panel, click on settings.
There is a section for additional menu items. You can enter a name to display in the menu, and a URL for it to link to. For example, you may want to link people to information about packages that you sell.
After you enter the names and URLs, click save changes. The names will display in the menu bar of the proofing events.
