Hi Tom,
We are planning to build something more convenient along these lines in with Enketo web forms in the future. At the moment the best way to skip between questions in a large form is either the 'go to question' button in KoBoCollect (which will list all questions without skip logic as a flat list).
For both Collect and web forms you can also create the form in a way that requires the interviewer to tick an opening question (using the Acknowledge question type) before going into the section itself. then just put the following questions into a group and apply skip logic to hide the entire group unless the previous question is ticked.
Best,
Tino
