[Feature] Import/export option #28

💡 Feature Description

Hi there.
Thank you for the great and helpful app!

Could you please implement import-export option to be able to transfer configuration to my other phones? Or to keep such file as a backup.
Also it would be nice to be able to specify password and encrypt such file during creation (export). And decrypt it when you import such file to new phone.

🤔 Problem Statement

I can't transfer my current configuration to other phones. And I can't make a backup.

🛠️ Proposed Solution

To implement such option.

📊 Benefits

• usage simplification
• reliability (because you have a backup somewhere)
• quick export-import procedure for your new phone

Thanks in advance.
