I wholeheartedly concur that Batch Optimize would be much appreciated, and would also suggest that when I click 'Optimize PDF' that it, wait for it, optimizes the PDF. It's frustrating that (deep breath) the button creates a new file but does not close the old one then initiates 7-step process to do what the button says, which should really be just the one step. It'd be much preferable to have the program do what the button says, not some roundabout, convoluted way of creating a smaller file. The above process would better be incorporated into the 'Save As' interface or thereabouts. Please let me click the Optimize button and have it optimize; I have to do this with every scan in my office.
Also Batch OCR would be helpful too.
