• One-tap password generation: create a strong password right from the keyboard while editing
[Improvements]
• New keyboard toolbar: quickly jump to the previous / next field, and dismiss the keyboard with one tap
• Search now matches tag names
• New "Display" settings page to customize how tags appear in lists and details

• Localization improvements
