Save place in tree
If I am in the middle of a lesson, and I leave the lesson to look up a definition at another website, I have to start the lesson over when I come back to Duolingo. Is there some way I can save my place in the lesson? I use a Mac with Safari browser.
Safari supports tabs. Just make your search in another tab and you won't have to leave and restart your lesson.
When I first started with DL, I found this out and was very frustrated. Now I use a different tab, but still there are some times I forget. It can be frustrating to loose all your work.
