The final number of CPLs shouldn't (forcibly) be all possible combinations of audio language and subtitle language, since a combination DE-VLS, for instance, wouldn't serve much of an audience (to be honest, my example of FR-VLS is not frequent either, on an American title, Flemish AND French subtitles are more common than a French overdub with Flemish subtitles). Same with FR-FR or DE-DE.
Yet, if there are X audio languages and Y subtitles on play, a minimum of X+Y-1 combinations would make sense. That would be all audio languages in use, and all subtitle languages in use with at least one audio language. "+" / "-" signs for customizing would make sense afterwards.
Right, I was imagining a button to add or remove VFs from the table, rather than automatically adding any.
In regards to audio, and especially for masters with discrete audio channels or separate files, assigning would still be a thing.
Ah yes, good point. I guess you'd need a drop-down (to choose the content file) and a way to edit the mapping.
Having the OV according to the smaller DCP size could not work if there is -say- an English 5.1 with a Spanish 2.0 overdub. And if one goes with the prompt to choose 8 or 16 audio channels, the output would be the same. The other way around, having the biggest package, would probably auto-pick the Atmos version as OV. Not a catastrophe, but not ideal either.
Maybe there's something cleverer (perhaps "choose the OV which minimises the total size of all OV + VF") or maybe you can just put OV on this list also.

Choosing the OV is probably the wisest.
More could be built to that. Like, choosing more than one CPLs for OV to send those CPLs to the combiner. But that would add complexity, that might not be necessary.

A question, here, is the viewing of the editor.
Meaning, how do you check what you are building on the viewer? Do you choose version, the same way you choose CPL on the DCP-o-matic Player? Or, toggle the active version from the versions' list?
Do you substitute the integral "Show graph of audio levels..." that is now on the DCP tab with that "active" version, or do you offer different buttons with that function by the version (OV/VF) list? (In which case, many, if not all audio graphs would have been the same, since many audio versions would be identical.) While the Content->Audio graph representation is useful, it's incomplete on multi-content or multi-audio-file compositions.

Right, yes I had forgotten that multiple VFs per project probably also means that you need to somehow duplicate parts of the UI (or, like you say, at least decide what you're looking at in the preview). I don't have a clear idea of how that would look. Maybe it's easier than I imagine, but I don't think it's trivial, especially as we really want to keep the "just make an OV" case looking the same.
