Work-In-Progress: Pull Request #182

New Autosave Feature for Avogadro

This pull request introduces a new autosave feature to enhance the user experience in the Avogadro application. The key aim is to reduce the risk of data loss by automatically saving the current molecule document at a specified interval of 5 minutes, especially in case of unexpected application closures.

Implementation Details:

• Autosave Interval Setup: Utilizes QTimer to establish an autosave routine every 5 minutes.
• Autosave Directory Determination: Automatically determines the autosave directory based on the application's data location preferences.
• Document Format: Saves the document in the CJSON format, ensuring a compact and efficient data structure.
• Unsaved Changes Detection: The feature is designed to activate only when there are unsaved changes, thus optimizing resource usage and avoiding unnecessary disk writes.

Integration:

• Updates to MainWindow Class: Incorporates autosave setup and execution logic within the MainWindow class, seamlessly integrating this feature into the application's core functionality.

This addition is expected to act as a safety net for users, securing their work without the need for manual intervention and frequent saves. The autosave feature is poised to significantly enhance productivity and data security for Avogadro users.

Hello maintainers
Introduced an autosave feature in Avogadro to automatically save work every 5 minutes, reducing data loss risk. Contemplating further UI enhancements to indicate autosave status and considering the implementation of a DESTRUCTOR for cleanup. Feedback on logic and suggestions for UI improvements would be appreciated
