This is already planned for a future version.

For now, you can try a third party hot corner tool: Mouse hotspot for activating Full Screen Preview

First of all, thank you for a great tool. I just love using it.

Second of all, I apologize if my feature request is already in the forum, I was not able to find it.

I would like to be able to use the mouse for more than just switching desktops.

For example, it would be very nice, if it was possible to activate full-screen preview by moving the mouse pointer to the lower left corner.
