There are several aspects I wish to change/upgrade in Locker PWM.

Desktop App:
The creation date and modification date are almost meaningless to me as an average user; I rarely pay attention to this data. These could be moved into the details section or replaced with a more meaningful code, such as 2FA or adding password expiration dates to remind users to change their passwords.

The ability to view details or edit requires selecting an action option, which is inconvenient for immediate use. I recommend adding at least two buttons for "edit" and "share" directly on the top right in the detail section, and increasing the width of this form for better usability.

The action selection areas in the list are too small, often requiring careful clicking to access. Separating 2FA into a standalone feature is a great improvement. However, the usability needs enhancement; when adding an account, the 2FA code should be entered manually or via scanning an extension or camera, allowing it to be automatically added to this section. The current requirement for manual entry seems cumbersome. The 2FA feature should display more information, such as the linked email, service name, and especially icons, as visual representation would enhance clarity.

When I share a note, I am surprised that it only shows a single line. This issue needs to be resolved promptly.

The tools (Password Generator, Locker Private Email, Authenticator, Password Health, Data Breach Scanner) should be separated from the Vaults section. Moving them closer to the "Live Chat" functionality while relocating the settings and import options into the menu would be more logical, as the settings are typically used only once during the initial app setup.

Allowing users to customize icons like in KeePassXC would be ideal. Adding a Favorites feature would also be beneficial.

Mobile App:
Home Tab: Allow users to customize the display of frequently used items.

Notes tab: The notes section needs to be enlarged, allowing users to manually resize it during input.

Private Mail: Allow users to add recipient email addresses, as some information is only intended for one-time use and I would prefer not to clutter my primary inbox. It would be useful to customize temporary emails for ease of remembrance, e.g., when I register for a service like Netflix, I would like it to look like Netflix.abcde@maily.org.

Finally, I wish you and the development team all the best for creating a quality product. I eagerly anticipate positive changes in the near future.
