The realization of Change in Inputs, and vMix's new handling of nonexisting devices (offline), made me think that Exporting and Importing individual inputs would be possible. The latter either when adding a new Input, or when changing an input, by importing a previously exported input. Another thing that I believe would benefit from importing and exporting is Shortcut sets (ie all shortcuts defined in a preset).

At this stage in thinking I guess managing single camera inputs this way is relatively easy. The same goes for shortcuts. Whereas virtual sets, titles, and list inputs might be more challenging.

Personally my need arose from the sort of standard multiviews we build and would like to use in different presets. I also have the need described in snedecor's request Way to make XAML items self-contained or able to be exported/imported

Anyone else that have similar needs? Do you think it is feasable?

I think the same. Power save configuration preset input, single, could be good for when you have, for example, several camera with various settings that are repeated for each input.
