Being able to pick the rendering intent in the LR export module would be great.
Now, if I want to change the intent, I have to export everything in a batch as PSD's or TIFFs and then use PS to batch change the color profile with the rendering intent I want. That's a huge time sink, especially given LR already has the capability of changing the intent in the Print module.
