 ## Features
 - [ ] Rename overridden methods automatically.
-- [ ] Rename type when renaming constructor method.
+- [x] Rename type when renaming a constructor method.
+
+### Warnings
+* There is no undo function when renaming with this extension.
+* There is no `unsaved changes` prompt when you rename with this extension.
+
+These are both part of the [AsmEditor](https://github.com/dnSpyEx/dnSpy/tree/master/Extensions/dnSpy.AsmEditor) extension, but the service used for these features is not public, so it cannot be implemented here.
