Just my first extension, to start with.
As I said before I still remember something from programming, but I feel lost in Android Studio. I’ve read a lot and seen a lot of good videos while ironing (free videos from Udacity Android development nano degree).
I’m a teacher and teaching block-programming is a good idea and Appybuilder is an excellent platform. If, at the same time, I learn more advanced stuff, it would be good.
I’d love to have an extension to add a grid view where it could be possible to add new cells and sort them manually by drag&drop with an smooth scroll.
Something like this: http://patrick-iv.github.io/2015/05/04/drag-n-drop/
