Key highlights: - Written from scratch to cater specifically to privacy.sexy's needs and requirements. - The visual look mimics the previous component with minimal changes, but its internal code is completely rewritten. - Lays groundwork for future functionalities like the "expand all" button a flat view mode as discussed in #158. - Facilitates the transition to Vue 3 by omitting the Vue 2.0 dependent `liquour-tree` as part of #230. Improvements and features: - Caching for quicker node queries. - Gradual rendering of nodes that introduces a noticable boost in performance, particularly during search/filtering. - `TreeView` solely governs the check states of branch nodes. Changes: - Keyboard interactions now alter the background color to highlight the focused item. Previously, it was changing the color of the text. - Better state management with clear separation of concerns: - `TreeView` exclusively manages indeterminate states. - `TreeView` solely governs the check states of branch nodes. - Introduce transaction pattern to update state in batches to minimize amount of events handled. - Improve keyboard focus, style background instead of foreground. Use hover/touch color on keyboard focus. - `SelectableTree` has been removed. Instead, `TreeView` is now directly integrated with `ScriptsTree`. - `ScriptsTree` has been refactored to incorporate hooks for clearer code and separation of duties. - Adopt Vue-idiomatic bindings instead of keeping a reference of the tree component. - Simplify and change filter event management. - Abandon global styles in favor of class-scoped styles. - Use global mixins with descriptive names to clarify indended functionality.
