Productivity mode is a display option in the Language page made for fast translation. Activating it strips down the POEditor localization platform to the most basic elements required to translate software strings.
To set the translation interface on Productivity mode, simply hit the red switch in the upper right corner of the Language page.
When the Productivity mode is on, only untranslated terms are shown, and scrolling down automatically loads more untranslated strings, until none are left to be displayed.
To go back to the default mode, just hit the Productivity mode switch again, and all the other features will reappear.
