Feature suggestion: "Card > Go Back" menu item / option in Actions

[Xkeeper0]

The documentation mentions that the go[] function takes several keywords; Next, Prev, First, and Last all have corresponding Card menu / Action items, but Back is the only one that only works in scripting and isn't available as a menu item/choice.

I believe the above satisfies the request.
Along the way I discovered and corrected a rather nasty bug related to the recently-added transition preview feature.

Does that also impact the Card menu? I'm not well-versed in Decker's code but that commit seems to add it to the Actions dialog box only, not the Card application menu. (I might be wrong, though)

Ah, I missed that aspect of the request. Easy enough to add.
