 - Error Handling: Enabled/improved error recovery systems. (#1651, #5654)
+  - Error recovery is provided as a way to facilitate:
+    - Recovery after a programming error. Native code or scripting language (the later
+      tends to facilitate iterating on code while running).
+    - Recovery after running an exception handler or any error processing which may skip code
+      after an error has been detected.
   - Error recovery is not perfect nor guaranteed! It is a feature to ease development.
+    You not are not supposed to rely on it in the course of a normal application run.
   - Functions that support error recovery are using IM_ASSERT_USER_ERROR() instead of IM_ASSERT().
-  - You not are not supposed to rely on it in the course of a normal application run.
+  - By design, we do not allow error recovery to be 100% silent. One of the options needs to be enabled!
   - Possible usage: facilitate recovery from errors triggered from a scripting language or
     after specific exceptions handlers. Surface errors to programmers in less agressive ways.
   - Always ensure that on programmers seats you have at minimum Asserts or Tooltips enabled
