Sadly, clicking the fast forward feature takes us to the interface for automatic tests, and there doesn't seem to be a way to return to the interface for manual tests.
You are right, once you choose the option Fast Forward, you are basically converting the test from manual to automated and I agree that once you do this, you no longer have the ability to add these notes and screenshots, and you can revert this test back to manual.
is a feature request I logged from your suggestion, feel free to vote for and track the progress of this feature using the link.
Statistics, results and reports seem to be exclusively based on test lists.
The reason why we take into account only the results from test lists is because quick execution is usually used when you are creating the test and you just verify that the test is working. Once the test is created, you should use test lists for executing these tests on a regular basis.
We appreciate your feedback, which we rely on to improve our product.
