Ekzamer - Social learning app

I have created this app in almost 1 months and i know there are some bugs. But i love kodular and i will work on this project to make it more perfect. So please install this app and tell me some features that i can add in this application. This application is a social app where you can ask your subject question and answer those question you know. It is created for school students. I will publish it in playstore soon as posible.
