We frequently enable floating windows for Audio Mixer, List Editor, and Slide show in order for example to adjust an audio level, uncheck a List item or selectt a Slide show item. When doing so Windows' keybaord focus remains in the floating window, thus vMix keyboard shortcuts are not effective (until the operator clicks in vMix's main window).

I think it would be better if all floating windows set the focus back to vMix main window after the action is completed within the floating window.

Ice,
Efficiency is in the eye of the beholder ;) For us the keyboard is very very often very effective.

My phrasing "after the action is completed" is of course dependend on which action/s the operator is taking.

Our most common fast-paced need is selecting a slide show image or a list entry. This is done by a mouse (double) click, and I see no reason for why here the focus cannot be returned immediately to the main window. For other actions, "when" would be rather logical depending on the action. This could of course be discussed (how/when), but I see no reason to do that before there is any interest in this particular request.

cheers :)

You may already know about this but you can use Auto Hot Key to direct keyboard shortcuts to a specific window. I used it for my XKeys before vMix added native support.
