We were experimenting with this feature and decided not to keep it based on how many users were coming back to the site.
Bren could you expand your logic please. What do you mean by 'based on how many users were coming back to the site'? It was a useful feature so why remove it?
We measure the fraction of users who come back to Duolingo on consecutive days. This fraction was lower for users who had the button to the extent it is unlikely to be explained by statistical noise.
There's no causal explanation as to why a smaller fraction return, although you can dream up explanations such as new users should focus on revisiting previous lessons over advancing quickly in the tree. Is that really the case? We don't know because we weren't testing that hypothesis.
Bren, different subject here, but what happened to the Progress Quiz? Many people (on a different thread) have been wondering what happened to it, and after paying lingots for it, want to have it back as it's an excellent way to measure progress.

indeed. it saved us time to scroll down. this needs to be fixed fast.
It's not that bad I've got the mobile and you just click on the skill and click on the next lesson it only take like 10 seconds longer.
i know but we have to scroll down and click twice and now it looks so plain >.<
