Drop down terminal when mouse hits top border of Desktop

I would like a drop down terminal which drops down when I move the mouse to the top (or bottom, left, right), similar to how the panel can be configured to auto-hide and only drop down or pop up if the mouse hovers to the border where it is. Currently I only found a [method](http://ubuntuhandbook.org/index.php/2014/02/launch-xfce4-terminal-in-quake-style-drop-down-mode/) using shortcuts e.g. F12 to bind to e.g. xfce4-terminal --drop-down. I'm using XFCE 4.12, but I'm not particularly fixed to XFCE or xfce4-terminal, so if some other desktop or terminal supports this, it would also help.
