- It would be nice to be able to tag users and a "reply" button on comments.
- See what users are online so you can challenge them, and diminish the risk of expiration of sent challenges.
- I'd be delighted if they came up with an "Android App Development" course.
- Perhaps a progress bar for each badge. Just so you can estimate how much effort/time you'll need to get them.
- Video lessons would be mind-blowing and deeply appreciated.
The more I play the more requests I come up with. I might be editing this comment in the future 😳 but I'm pleased with all the latest updates 😉
