great work, but half of the sticker / emoji panel is off of the screen so you need to get the contacts panel back in order to use it.

Works well to recover some space for the chat window. Only a thin vertical line remains on top of the chat where the edge of the left panel used to be.

Also, the screenshots seem to be out of date. The hide button is now a button revealed on hovering over the right edge of the contact list. I thought it was not working at first, because there was no "crossed-out eye" icon in the left panel as is shown in the screenshots.
