Another update seems unlikely.
As a workaround, if you uncheck all the categories, minimize the window size, move it to the top right corner behind the mini-map, then click the 'Allow clicking through log window' icon, only the small lock and eye icons will be visible (barely noticeable) in the corner. The background of the box will only show up if you mouse over the mini-map (or close to it) on the left side, not from the bottom.
You can not move it permanently to the very top of the screen/window (reloading will move it down so it doesn't get much higher than the top of the Log and Game Menu buttons, but it will still be mostly out of the way and usually invisible.
