Along the top of Observatory’s window is the Toolbar. Packed with buttons and fully customizable the toolbar makes it easy for you to collect and organize astronomical images.
At opposing ends of the toolbar, you’ll find buttons for hiding and showing the Sidebar and the Inspectors. Above those, you’ll find the standard macOS window controls for closing or minimizing the window or entering Full Screen mode.
At the center of the toolbar along the top, you’ll see an Observatory library document icon and its filename. If you hold down the Command key (⌘) and click that icon or filename, you’ll get a tiny menu that shows you where the file is stored on your Mac. This is sometimes handy for when you’re working on duplicated files and you can’t remember where you saved the last revision. Another use of the document icon is that you can drag it to the Desktop or a Finder window to create an Alias to the file.
To the right of the filename is a small chevron. Clicking it opens a small popup window, in which you can change the name of the file, add tags to help make the file easier to find using Spotlight, move the file to another location on your Mac, or even lock/unlock it.
To hide the toolbar, choose View ▸ Hide Toolbar or Control-click on the toolbar and select Hide Toolbar. Alternatively you can also just press
⌥⌘T. Repeat this to show it again.
To customize the toolbar, choose View ▸ Customize Toolbar or Control-click on the toolbar and select Customize Toolbar. When you do, a sheet slides down from under the toolbar, revealing a slew of function-related buttons that you can drag up to the toolbar. When you’ve finished making changes to the toolbar, click Done.
If you don’t like the changes you’ve made, or if you ever want to reset the toolbar to its default set, all you need to do is drag the bottom row up to the toolbar and then click Done to save the changes. The changes you’ve made to the toolbar are saved along with Observatory’s preferences, so that you’ll see the same toolbar options with every library document you create.
