 - _Rerun generator_: Reruns the generator with the new values specified.
 - _Save last input to file_: Saves the sequence of bytes that produced the last generator result to a file. This
     file is just a binary sequence that can be fed to any generator, and can be used with Zest's ReproGuidance.

 - _Rerun test case_: Reruns the test case using the most recent generator output, updating the collected coverage data.
 
 ### View Settings

 These options control how program locations and their corresponding values are displayed and formatted.
 - _Show type-level decisions_: When checked, instead of displaying a single entry for each individual byte, a

 If a generator caches intermediate computations that invoke `Random` methods, then rerunning the generator twice with
 the same underlying byte stream may produce different results (this is a limitation of JQF as well). More broadly, any
 generator whose output is not solely a function of the input pseudorandom byte stream will exhibit this behavior.

+### Custom serializers for generators
+Currently, the generator output displayed on the frontend is simply the result of calling `toString()` on the produced
+object (truncated to 1024 characters). Custom serialization functions are supported but not yet exposed to the
+command-line interface - please file an issue if this is a feature you need.
