I would like to see a new function. Selected and already edited photos again as unedited so original photo as JPG to export. If you have selected and edited 500 out of 2000 photos and the customer suddenly has the desire to also request the originals, it is tedious to hand over the ready 500 selected in unedited state, i.e. original JPG.
If the original is a jpeg, then you already have this option. You can select 'Original' as file type in the export dialog. If the original is raw, then my answer to that client would be that he can't get my raw files, period.
