Syncing two staging enviroments concept

Recently I worked on an app that requires two steps to be released to the public, every time an update is made by the administrator.

Firstly, any new app entities must be uploaded to the stage environment to check if anything new is operational and bug-free. After checking, the user must write down those new changes per app-section, create a screenshot of each app section, and import them to the public state of the app.

The suggested concept removed all the manual tasks (write down, export-import screenshots). Simply we create a small, notification-like section where all new changes are saved and listed. Then, the user can select all the new changes that wish to move to the public environment.
