Published timers will appear on your website and unpublished timers will not. There are two ways to publish and unpublish timers.
Publishing and unpublishing timers from the dashboard
Published and unpublished timers appear differently on the dashboard. Published timers have a pretty blue-purple gradient bar on their left edge and show metrics on the right, indicating total lifetime clicks (if they have a link) and views.
(We know, the click-through rate of this timer is downright embarrassing. We're working on it.)
If they're unpublished, they feature a grey bar on the left, grey text, and in lieu of any metrics on the right, a message staying they're unpublished and will not appear on your store.
To change a timer's publish status, you can hit its "…" button, next to its EDIT button.
Clicking "..." will open the actions menu, listing a handful of convenient actions. If the timer is already published, then the first action you see will be Unpublish. If it's already unpublished, it will be Publish.
Clicking it will either make it go live or go dark on your store.
Publishing and unpublishing timers from the editor
Publishing and unpublishing timers can also be accomplished in the editor. To open the editor, hit the EDIT button on the timer you wish to change the publish status for.
With the editor opened for your timer, you'll find the Published option at the bottom-right corner of your window.
It has a little scroll attached to it, if you click that it will take you to the option of either making your timer Published or keeping it Unpublished from your store.
If you wish to publish your timer make sure the Published button is checked, and if you aren't quite ready to show this timer off, then keep it Unpublished until you're ready. You will see in your dashboard that the timer will reflect the choice you made, if it has a pretty blue bar beside it you'll know it's definitely published, and if it's looking grey it will be unpublished.
