Fixed in https://github.com/badbundle/vault-app/pull/597 (merged as e54eb1e0).
- Password first: the screen now opens with a centred header ("Choose a Backup Password" or "Choose a New Password") and goes straight into the fields and the Set/Change button. The field is focused after authentication, and Return moves through the fields and submits.
- No more drop-downs: a single "About Backup Passwords" row opens a details page. It has help questions that open Markdown documents the same way Settings > Help does: the new
Backup-Password.mdandBackup-Password-Changing.md, plus the existing backup security FAQ. It also shows the key generation info. - Navigation: the sheet owns its own navigation stack, so opening the details page and coming back keeps what you typed and doesn't ask you to authenticate again.
