FWIW, I don't think there was any functionality (aside from switching to FIT_IMAGE_TINY, but if that supports everything needed in this use-case...) that was removed exactly. But I see your point too. Jean-Jacques, was there anything else that could have been made configurable in your MMC work, that wasn't? Thanks! -- Tom
