SSH agent support really needs to be in EnPass. Sure, most casual web users won't need it. But power users do. What better way is there to attract more users to the product, than to have strong advocates in the SME community? Also - Yubikey.
Yubikey support seems like the Enpass development team's "Duke Nukem Forever". C'mon folks... you built support for passkeys. Now how about some additional protection for vaults with some good ole' FIDO2? And if your business model won't support it, how about just open-sourcing the product, shuttering the offices, and letting other people do it? It would be done in a week.
