Toggling / switching among languages
It would be great (and probably an easy fix) if duoLingo could make it easier to toggle among various languages being studied.
Maybe create a button for this, or make the language flag/icon into a toggle-able button? Maybe create a greyed-out icon for languages we'd like to begin studying, and Technicolor it once the language gets out of the laboratory and is activated?
Submitted for consideration.
You could give the Language Course Switcher a try. Read the complete thread as the there are suggestions to change it to meet your preferences. I really haven't used it because I don't mind the few steps it takes to switch. The time it takes gives me a bit of a brain break from studying.
