+- must have:
+    - explicit order of:
+        - outgoing transitions
+        - regions in AND-state
+
+- usability stuff:
+    - highlight selected shapes while making a selection
+    - comments sometimes snap to transitions even if they belong to a state
+    - highlight fired transitions
+    - when there is a runtime error, e.g.,
+        - variable not found
+        - stuck in pseudo-state
+        - ???
+      don't crash and show the error
+
+- experimental features:
+    - multiverse execution history
+    - local scopes
