Enhances grid view selection to optionally target only visible items when a filter is applied, preventing accidental selection or deselection of hidden rows via the header checkbox. Updates the save logic to process the unfiltered master dataset, ensuring that previously selected but currently hidden items are safely preserved during save operations.

.SYNOPSIS
|
|
Provides a collection of shared helper functions for manipulating WPF UI controls, handling asynchronous updates, and managing common UI interactions.
|
|
.DESCRIPTION
|
|
This module contains a variety of reusable functions designed to support the FFU Builder UI. It includes utilities for managing ListView controls, such as sorting, reordering items, and handling 'Select All' functionality. It also provides thread-safe mechanisms for updating the UI from background tasks, wrappers for modern and classic file/folder dialogs, and generic functions for clearing UI content. These shared functions help to reduce code duplication and ensure consistent behavior across different parts of the application.
