Pull Request

Description

This pull request introduces improvements to the Flatpak installation script by adding user interaction features, such as a selection menu and confirmation prompts. These enhancements aim to provide a more user-friendly experience during the installation of Flatpak applications.

Summary of Changes

• Added an interactive menu to allow users to select specific Flatpak applications or install all at once.
• Implemented a confirmation prompt to review choices before proceeding with the installation.
• Added error handling for cases where the application list is empty or invalid.
• Included setup commands to ensure Flatpak applications have access to GTK themes and icons.

Motivation and Context

The previous script lacked user interaction and always installed all applications listed in the configuration file. The new script allows for more control over the installation process, making it more flexible and user-friendly.

Dependencies

• No new dependencies are introduced. The script relies on existing functions from global_fn.sh, specifically pkg_installed.
