Embodiments relate to enabling users to provide feedback on resources displayed in user interfaces. A feedback tool is executed to allow a user to specify a resource displayed in a user interface. Context metadata about the user interface is captured and stored by the feedback tool. The context metadata corresponds to runtime activity such as loading executable modules, rendering the user interface, handling windowing/input events, etc. The tool is used to specify a resource displayed in the user interface. This triggers capture of the specified resource and the runtime context metadata. The resource and context metadata are searched for in a database of known resources and their respective properties and identifiers. If a match is found, then the source-level identity of the resource is known. The feedback is associated with the resource and used to directly supplement or modify the resource in a source code resource file.
