I'm not that concerned about Quiver not being open source, as its note storage format is simple & documented json. Should there be a reason to move away from Quiver, it would be pretty simple to construct a way of transferring notes (assuming the destination is as transparent). In the meantime, it's quite a pleasure to use: very fast, well-presented, and with carefully-considered interactions.

I must give Boostnote a try. On the face of it, I would think an engineering notebook, to be used daily for large amounts of stuff, would be a paradigmatic case for a native app like Quiver rather than electron. But then there's Atom & vscode so maybe not? And I'm a bit uncomfortable with Boostnote's copyright transfer for pull requests (https://github.com/BoostIO/Boostnote/blob/master/contributin...). But then again, I pay little attention to copyright matters so perhaps just haven't noticed if this is common in open source. And it's clearly nevertheless more open than Quiver.

I've just given boostnote a quick tour, as a Quiver user I'm not so sure boostnotes is quite there yet, at least on feature parity.

There seems to be some UI slowdown on my machine too, whereas Quiver doesn't seem to suffer from that at all, and I have like 200+ note files in my Quiver repository!
