 <H3> events </h3>
 <p>
-At the moment all events need to be local.
+Event callbacks get a (rnd_design_t *). There are two kind of events:
+<ul>
+ <li>per-design: the event affects a specific design only; most often called
+               for the current design, but callbacks shouldn't depend on that.
+               Examples: RND_EVENT_SAVE_*, RND_EVENT_DESIGN_*.
+               Marked as [d].
+ <li>per-app: the event affects the whole application and the design pointer
+            passed is irrelevant (points to the current design).
+            Examples: RND_EVENT_NEW_DIALOG, RND_EVENT_BUSY.
+            Marked as [a].
+</ul>

 <H3> config change callbacks </h3>
 <p>
 With config swapping this is granted; however the API lacks hidlib passing.
