For users who want convenience, it should be possible to save crypto keys in their browser so they can be reused later. This will improve convenience at the expense of security, but should fit well with the app threat model (assuming that your device is secure).
It should be possible to opt-out for those who only wish to keep their crypto keys in memory during app usage, but never save to persistent browser storage.
