I'm not really certain how this feature is called, however many editors (including Netbeans) allow jump from the function name in the code and automatically set cursor on the function implementation code, automatically open the file if not located in the current one. Usual combination is Ctrl+Left Mouse click from the pointed word/function name inside the editor text.
That would be very useful if some user made lib, or even official shows some problem to be easily open and modified. Especially during process of making such library, as IDE opens automatically only files located inside project root directory.
Another connected case is when compilation fail with error. Currently, compiler's output is inside text container, then need to copy path etc, in order to open the file. Much easier approach is to additionally allow another list box where on single click message could be parsed and jump/reopen exact file and set on line where the error/warning is.
