Spending quite a bit of time using the desktop view within Dash and one action I can not figure out, on the Windows 10 taskbar as with previous version there is an ^ bottom right that brings up hidden programs running steam, voice attack and other things, I have yet to figure a way to access that in the desktop mode, I can hover over it, use the same trigger I would use to select and run things but it will not raise and show what is hidden. Out of that desktop it is a simple left click (show hidden icons).

touch controllers seem to work fine as a mouse for everything else but this quirk means anything minimised is unavailable.
