Can you send quests for yii2?

Question

Yii

Good day, I have a free two weeks and I would like to spend it on creating something new in yii2 purely for practical purposes for myself. The fantasy itself is rather weak, and the latest projects were quite the same type of IM. Just without criticism - what is new to do for yourself to improve your skills with yii2, go even deeper into the framework?
I'll be happy to do tests :)

Answer 2

Do something socially useful. You can take part in the development of yii2 itself. You can write a module or widget that will be in demand by the community. Surely you have a bunch of developments that need to be "polished" and can be uploaded to github.
