Remove "Show Desktop" button in Windows 10 Tablet mode

In Windows 10 in tablet mode, if the show desktop button is set to a custom size (I like to do it a square 40px, it still takes up space on the taskbar even though in tablet mode there is no desktop, thus this button doesn't do anything. So that's just empty space being wasted. I suggest adding an option to remove the button when in tablet mode (something like this seems a good candidate to also have set by default).

I have attached a screenshot as an example (bottom-left corner).

Thank you,
A grateful user
