Touchscreen: closing the window w/o running a program

[ibrahimbayyinah]

Firstly, thanks for this great tool! I just installed it a couple minutes ago and I love it so far.

From the README:

To close the window w/o running a program, you may use the Esc key, or right-click the window next to the grid.

Is there such a thing for a touchscreen? To close it using touch gestures w/o running a program.

I read in other issues that you don't have a touch display yourself. So if it's not something you plan to support, I will create a .desktop entry which just fails, as a potential solution.

Thanks in advance.
