Gitoqlok Helper window in the App overview reveals the Tags Manager feature:
Gitoqlok Helper: Tags Manager
You can see all of the current application sheets displayed in the opened modal window. Columns "Tag" and "Published" reflect the status of the sheet and whether the sheet is published correspondingly.
Gitoqlok Helper: Tags Manager
There are three tags options you can set for your sheets:
Private
Not set
Public
Once the private sheet is tagged "Public", Gitoqlok will identify the discrepancy and highlight the "Published" checkmark next to the sheet.
If you check the box your current sheet will be actually published.

When you are done editing the sheet tagged as "Public" Gitoqlok will, too, notify you to not forget to publish your sheet.
Tag Manager notification
When you publish your application through Gitoqlok right from the Qlik application tab, you are going to be notified about having sheets with a "Public" tag being private and suggested to publish them:
