Description

We implemented a FindChildrenAction that

1. builds a hierarchical structure of a selected feature and all its child features
2. collects usage references for each feature in the hierarchy
3. displays usages grouped by feature
4. supports recursive child discovery and usage aggregation

Motivation and Context

When features have multiple nested child features, manually inspecting each one to find code references becomes time-consuming. This action simplifies code navigation by a right click on the selected feature and automatically gathers all usages of a selected parent feature and its entire hierarchy of child features in one view. Developers can now instantly see how a feature family is used across the project. This centralized overview helps maintain better mental models of feature relationships while reducing context-switching during code analysis.

How Has This Been Tested?

• Tests are created and passing
• Manual testing
  We executed the "Find Feature Children" action manually in the feature-model-feature.file in the Snake project.
  We did two kinds of tests:

1. feature with children features
2. feature without child
   In the first case, it displayed usages of the selected feature and its children features in the window.
   In the second case, we ensured that no children from other features were shown, only the usage of the feature itself is displayed.
