I only have access to Notezilla through the Notezilla browser. How can I get the tray icon that opens new notes, preferences, etc?
Right click on Windows taskbar, go to Task Manager. If you see "More details" option at the bottom of the window, then click on it. Now click on Processes and check if Notezilla .exe is listed. You can kill the task (end task) and try running Notezilla again. Now let us know if the icon appears in the task bar, next to the clock.
