Yes agree on the shortcut 'for free' aspect, but I'd consider expunging unused default menu items as part of a very basic pre-release checklist, rather than 'polish'. I don't share the frequently-expressed antipathy to electron apps, but many are quite shoddy, which only adds to their poor reputation. I've seen commercial apps which (for example) replace their whole window contents with a dragged image.

I'll keep an eye on Bitwarden - I like the overall shape of the project, but it's not ready for me yet (had some problems with the firefox extension also).
