When the 2 options for Save image to tag and Save image to disk are hidden behind a right-click often times I forget to change them.
It would be nice to have them exposed to the main Adjust tag info UI.
Even have them all in the panel on the right-hand side.

I've added the first entry to the main UI with Mp3tag v3.13
added support to enable and disable import of cover art via checkbox at Tag Sources confirmation dialog.
Not sure about the second entry though, I don't want to visually clutter the main UI too much. It's already confusing for some.
IMO, I think leaving out 1 of 2 options exposed is more confusing. The artwork is nicely separated from other UI elements so I don't think it would be too cluttered.
