nordicsimply review for Promo.com ‑ Promo Video Maker

The Promo Video Maker app is very easy to work with. I am wondering why it isn't possible to download a video instead of publishing it right away? Also wondering why the video maker doesn't save a copy of videos that are published (in order to edit it for future publishings) - As far as I see I need to create the video again from scratch if I want to make changes for future publishings...?
