Ability to Delete Triggers Across All or Named Slides

Idea:
Provide the ability to delete all/selected triggers across all slides or specific named slides in a single action.

Current limitation:
Triggers must currently be deleted manually on each slide. In large courses (e.g. 300–400 slides), this is time-consuming and error-prone.

If a trigger needs to be removed (e.g. outdated variable logic or navigation):

1. Each slide must be opened individually
2. The trigger must be located and deleted manually
3. There is a risk of missing slides or leaving inconsistent behaviour

This process significantly slows down updates and increases the risk of errors.

Suggested improvement:
Allow authors to select a trigger (or trigger type) and delete it in bulk across:

• All slides in the project
• Specific scenes or named slides

Optional enhancements could include:

• Filtering by trigger type (e.g. variable, jump to slide, execute JavaScript)
• Previewing affected slides before confirming deletion
• Undo support for bulk actions

Use case:
When updating course logic or removing redundant functionality, developers can quickly remove triggers across the entire project without manually editing each slide.

Benefit:

• Saves significant time on large projects
• Ensures consistency across slides
• Reduces manual errors and missed updates
• Improves efficiency when maintaining or refactoring courses
