Hot Corners

I thought it would be good to have an option to use one corner for two different task. This would be helpful if all other corners are already in use

Example:
Top left corner:
1) Icon visible (activates when pressed on)-> Show all workplaces
2) Hover enabled (activates when hovered over)-> Show all windows

Also it would be good to have an option to add a wanted program into the list of what to do(and also choose which way to activate -> Hovering/Pressing).

Example:
Bottom right corner
1) Icon visible (activates when pressed on)-> Firefox
2) Hover enabled (activates when hovered over)-> Calculator...

Also it would be nice to have an option of time responsiveness of hovering(sometimes i hover by accident and task activates) P.S. There is a tweak which allows it, but it would be nice to have it without additional tweaks.
