Please add a possibility to select the standard filter („auto“ etc.).

Whiteboards with circuit diagrams have many lines missing because brightness or contrast can't be adjusted.

I just need my pictures of documents to save not as yellowish due to environment lighting, AND NOT BE 900kb in size when such documents should be saved under 100kb with an office scanner (grayscale or b&w). Therfore grayscale, b&w, or contrast features would be great AS LONG AS THEY ENSURE THE DOCUMENT IS SMALL IN SIZE. Right now i tried to use my cell phone camera with grayscale setting then printed that to pdf but the size was bigger than what Office Lens was producing (2.7Mb vs 800kb). Still, 800kb is way too much for a simple PDF document intended to be black & 2

Please add simple background removal (remove shading due to paper folds and uneven lighting)
Perhaps efficiently done using "rolling-ball" morphological filter or using primitive high-pass filter, followed by a B/W threshold.

Please add the ability to manually regulate the brightness and contrast settings (or enhanced auto whitening background)
