Yeah full disclaimer. I started working on it before I saw bvckup2 and then at some point came across it and then could not unsee it design wise so you're right. Some things are very heavily inspired off their awesome design.

Outside of the main window though, lots of other things are quite different and completely independently arrived at. Bvckup2 doesn't have third party storage support so everything else requires a fundamentally different UI to work in BlobBackup. Look at the settings windows and the menus for example.
