wanted: navigation best practice

Hello everyone,

I'm currently working on a multi-part WBT series and am looking for a best practice on navigation.

My current approach is as follows:

• During the first pass, the Next button is locked until the audio has been played in full.
• The "Replay" function is available, but when replaying, the Next button remains locked until the end.
• From the second pass onwards, the learner can navigate freely. To do this, I set a variable ("Replay") on the last slide that globally unlocks the Next button.

Question 1: Are there better or more efficient ways to enable freer navigation directly (possibly even on the first run) without necessarily waiting for the replay variable?

Additional Challenge: "Replay" in Interactive Situations Problems arise in the interaction between "Replay," triggers, and states in the following cases:

• Custom interactive elements (e.g., sliders)
• Drag & Drop Exercises
• MC/SC Questions with Feedback Logic 

Question 2: How can clean behavior be achieved in such cases without triggers or states getting confused – especially when the audio is replayed or the slide is called multiple times?
