Same here. I switched from LastPass and I really like the UX more than LastPass. It is less intrusive and feels more polished and snappier.
But that said, it is by far the best product despite this.
Bitwarden clients have the same UX across OSes and platforms ( browser extension, mobile app, thick client". The thick clients are indeed Electron based.
I'm actually a bit confused by 'the same UX across OSes'. What does this mean? The mobile UI is completely different to the desktop apps and web app.
Props to the Bitwarden guys for fixing the only thing that really bothered me with the UI.
