Hello HoRotem,
Thank-you for your question.
Basically there are a few ways you can update your Zapfree based tests:
1. You can do another recording while the current test is still opened, and this will add more steps to the same test.
2. Do a right-mouse-click on any step and add new Wait step (With such click you can also remove existing steps).
3. In the Workbench (Added to Zapfree in the latest v15.0.37) you can update the different captured objects during the recording phase,
Please contact Zap for further help.
Thanks,
Sasha
