Add "Read Time" Field Storage in Database

[JaneConvergine]

Hello,

We are using your "Read Time" plugin and would like to request a modification. Specifically, we need the plugin to add an additional field for the "read time" value on every article entry. This value should be stored in the database, allowing us to use it for filtering functionality on our blog page.

Thank you for considering our request. We believe this feature would significantly enhance the usability of your plugin.

Looking forward to your response.
