   ### Proposed Improvements
   
   - **Text Search (within DAG code)**  
     ↪ Enables quick lookup of task IDs, parameter names, function names, or 
config snippets
   
   - **Toggle for File Diff (across DAG Versions)**  
     ↪ Helps users understand changes introduced between versions (especially 
when troubleshooting regressions)
   
   - **Section Filter (e.g., show only task definitions, schedule config, 
etc.)**  
     ↪ Useful when scanning long DAG files to focus on relevant areas (e.g., 
`@task` decorators, `@asset` functions)
   
   ### API Support  
   
   ❌ No
   
   - DAG source code is retrieved in full via the `/dagSource` endpoint.
   - No server-side support for search, diff, or section indexing currently 
exists.
   
   ### UI Impact  
   
   - Text search input could be added above the code viewer, with inline 
highlighting.
   - A toggle for DAG version comparison could enable unified or split diff 
views.
   - Section filters could be implemented via regex (e.g., jump to task 
definitions) or indexing during parsing.
   
   ### Notes  
   
   - Particularly helpful for large DAGs with many custom functions or inline 
logic
   - Would bring the UI experience closer to modern IDEs, improving developer 
ergonomics
   
   ### Committer
   
   - [x] I acknowledge that I am a maintainer/committer of the Apache Airflow 
project.
