Test Studio already has a built-in automatic "wait until ready" for all action steps (navigate, click, etc.). What problem are you running into? Are you perhaps dealing with an AJAX postback? Test Studio does not have a built-in mechanism to automatically detect these and wait for them to complete. We wrote this KB article showing you how to handier this situation using a coded step.
If you're dealing with a different situation, please clarify what the problem/symptom is so we can better assist you with the right solution to that problem. A video would help us see and understand the problem you are facing. Jing is a good and free screen recorder.
