+- Cluster Grouping for Policies
+  * Allow creating reusable cluster groups for multi-cluster deployments. 
+  * Define groups as collections of clusters or cluster label selectors. 
+  * Groups should be referenceable within existing Topology Policies to allow reusability and consistency across Applications.
+
+- Reusable Label Management
+  * Create labelsets using Config and ConfigTemplate for organizing governance data like teams, organizations, and cluster information. 
+  * LabelSets will be referenceable within Applications to better support governance requirements.
+
+- Crossplane credentials management
+  * Allow specifying cloud credentials for Crossplane integration via Kubernetes secrets.
