Description
Introduce functionality to save and load export configurations, enabling users to quickly resume work without reconfiguring settings manually. This feature enhances usability for repetitive tasks.

Proposed Features

• Add the ability to save the following settings:
  • Path to the MS Access database.
  • Selected tables for export.
  • Export preferences, such as inclusion of foreign keys and data filters.
  • Output path for the SQL file.
• Allow users to load configurations via a file or user interface.

Use Cases

• Reusing a preconfigured setup for recurring export tasks.
• Using as a parameter to run from the command line.
• Sharing configurations between team members for consistent operations.
• Reducing setup time for users managing multiple databases.

Work has commenced on the task. Currently, efforts are focused on implementing functionality to save (and load) the TreeviewDataFrame configuration to (and from) a JSON file.

This feature could potentially benefit tk.Treeview users as well, making it worthwhile to consider generalizing the solution for broader applicability.
Feedback and suggestions on this approach are welcome.💎

The implementation is planned for completion next week.

At app startup, the last saved configuration is loaded if there is a corresponding file in the working directory
