Include "Replace Video" Feature
At times a completed video, embedded in various places, requires a minor change. [Typo, content correction, minor adjustment.] Vimeo/YouTube offer a "Replace video" option that keeps everything the same--including the URL--but lets the user upload a new video to replace the first. Under Edit or Manage, if there could be a "Replace Video" and then "Upload or Select New Video" option, that'd rock.
I THINK this is possible by uploading a new video as a second stream, deleting the first stream . . . but it could be easier by including the Replace Video option.
