This isn’t so much a suggestion for the software itself, but rather a download method.
When I was trying to download the installer it took so long. My connection to the dl server kept timing out. Or my download speed would be around 50 KB/s and eventually just stall permanently. Why not add a torrent download to the site to save on bandwidth and server resources?
Just a thought. I almost gave up on the download when I couldn’t get the direct download to work.
Downloads through shotcut.org or shotcutapp.com (you did not specify) are provided by GitHub, which uses Amazon S3 and possibly as well Amazon CloudFront. If you have trouble with Amazon, it might have been a temporary passing problem, or you will suffer performance problems with many sites because… it’s Amazon web services. No plans to provide torrents at this time because that would actually require more resources for me.
