 ## [Unreleased]
 ### Added
 - Reference support for type names within aspect files.
-  - usages are now highlighted
+  - Usages are now highlighted.
 - Refactoring of type names now also works in aspects.
   - Note that although it works in the Java embeddings within aspects, it does *not* work in "real" Java classes.
   - Please use this feature with caution. As with most refactoring tools, it is quite fragile and won't give correct
     results in all cases.
 - Folding support for aspect files.
   - Aspects and most blocks now can be folded.
+- Structure view for aspect files.
+  - Attributes and inter-type declarations are shown sorted by aspect.
+  - There are toggle buttons to show or hide attributes, inter-type declarations and rewrites.
+  - Note that things outside aspects, equations and some other elements are not yet included.
