Mail Issue - Notification inbox automatically closes

[Andarific]

Currently, the mail notification inbox interface automatically closes after clicking the 'Ok' button on the mail message interface.

This can be an annoyance if the user wants to keep the inbox interface open to continuously view their mail before they decide to close the inbox. However, an option (in the form of a checkbox or setting option) could be implemented to allow the inbox to automatically close after viewing mail if the user wishes. Keeping the mail inbox interface open after closing the mail message interface would be set to default.

Tasks for this issue:

• [ ] Keep the mail inbox interface open after pressing 'OK'/closing a mail message interface.
• [ ] Implement an option to keep the mail inbox interface open or close it automatically after closing the mail message interface. Keeping the mail inbox interface open would be the default option.
