The updated emote menu in version 31.3.0 is not size-optimised and can only show 2.5 rows of emotes at a time.
You also can't send the message while being in the emote menu which is super odd, cuz the button for sending the message is visible and looks to be clickable, but clicking on it just closes the emote menu (and closes the keyboard altogether) and moves the send button to the bottom of the screen. Non-intuitive and a new problem that was created with this new update.

There is extra padding in multiple places in the emote menu that can be removed to make the useable emote window bigger: between the "emote | gif" buttons and the actual emote window; the grey strip under the emote window (the buttons are centered to the top, which creates deadspace underneath them that can be removed); between the textbox and the "emote | gif" buttons; and the "emote | gif" buttons themselves can be made smaller too. Maybe the "gif" button can be moved to the grey strip at the bottom too, this would free up a lot of space.

Please consider optimising these two aspects to make the emote menu intuitive and user friendly.
