 A better Help buffer.
+
+SCREENSHOT
+
+Helpful will:
+
+Always **show the source code** of functions. It shows the
+source code for interactively defined functions (unlike the built-in
+Help) and falls back to the raw sexp if no source is available.
+
+Display **symbol properties**. This provides visibility of features
+like edebug or byte-code optimisation.
+
+Show **references**. You can see where a function is being called!
