I've been using AWS S3 for sometimes, nothing to complaint except whenever I need to manage, I have to login, navigate to the bucket/directory. Upload/delete file also requires too many steps

Decide to built this desktop client. I can create a connection to an existing bucket (or create a new one), then start browsing/upload/delete files just like Finder or Window explorer.

AWS credential is required (with at least read/write permission). A macOS version is available, Windows version is on the way (do let me know if you interested).
