no issue - ~10x speedup in processing time taken on each keypress when there are many images/image upload components in the editor - edit DOM in memory before changing it in the page to avoid double-render - keep upload components around and re-assign them on re-render, adding or removing an image will still re-generate everything - adds a throttle to the preview rendering so that renders don't get queued up - fixes occasional bug where uploading an image didn't update the markdown correctly due to a timing issue
