scrolling to bottom is difficult since scroll bar is rendered behind the bottom navigation/status pane

I'm a bit concerned this will be exacerbated by my changes that hold onto file contents to upload (as the fact that we don't hold onto it today means it likely is garbage collected when the file is parsed). Some of the strategies I'm considering for dealing with this:

• stop holding on to file content, instead adding streams to the multipart upload, which request already supports
• by default, use createReadStream instead of readFile when parsing. We can stream off the first N lines for my file parsers and simply stream over all the content for the dicom parser.
