Grass is greener on the other side: view from Windows Phone 8.1

Hello folks, I am back with another inquisitive post. It has been a while, Windows Phone has seen three minor and one major release since then, the competition has improved in the meantime as well. A lot of feature wishes has been fulfilled with 8.1, a lot remains.

Like last time, With the risk of being too optimistic, I would like to ask Windows Phone users on this forum to say the features from Android and iOS(phone) they wish that were on Windows Phone too. Preferably in the order of priority. Maybe take a look at your past comments too!
