Concerning the recently used Emoji tab. I suggest we change the current behaviour of the Emoji button to opening a overlay popup similar to the one for attachments. This popup will always contain a button to open all Emoji but will continue to fill up with recently used Emoji either enlarging the popup to the top, or having them sidescrollable. On another note one could think about using a method to define favourites rather than autoadding recent Emoji.

This way we'd have a much less intrusive and fast option to insert Emoji with a shorter blend time and less to load in QML and also I'd suggest that on long press Emoji not only the Emoji is inserted but also a Space behind it!

Cheers
