This would be relatively simple to add, but I wouldn't want to have that as an option in the UI. Would a configuration-file option work and is there a concrete deployment planned that actually requires such an option?

I think it would be *nice* to have it in the UI, but I understand the reasons you might not want it. The reason it would be nice is that on support calls it's easier to tell the user to toggle an UI option, than to mess with a config file.

On the other hand, config-file-only option means users would be less likely to disable it themselves. So I can live with that!

Yes.

is there a concrete deployment planned that actually requires such an option?

I work with (and am responsible for information security of) a few hundred journalists at OCCRP who are pretty tired of Thunderbird. We are constantly looking for a decent e-mail client, and Kube looks very promising.

By the way, I had some (not a lot) experience with QML so if I were to be pointed in the right direction, I *might* be able to submit a patch for this.

Cool =) If it's a organization-wide policy the point would exactly be to not have to deal with such support calls, because you'd just always configure it that way for the deployment.

Great =) If it is promising enough we should probably have a look at what features are currently missing to make this viable for your usecase.

It should be possible to implement the necessary logic in framework/src/domain/partmodel.cpp (see TypeRole and ContentRole).
For the setting I'd just use QSettings
