How to move "Chat button" from the right to the left?

Hi,

is it possible to move the “Chat button” to the left side of the screen?

I mean this control:

I can explain why I request this changing: when I expand “Layers” toolbar, which is lowest on the right-side tool bar set,
the Chat button hides the layer’s On/Off buttons, so I’ve forced to scroll Layers toolbar to unhide them:

It is very annoying, hovewer the left side of the tool window is completely free and not used at all.

Thanks.
