Current tool is located at Models/data_utils/manual_audit_app.py and can be run by a simple Python execution.

More features requested by @aadarshkt :

• Add an undo operation, in case you wanna go back to those frames you got em wrong.
  - Yeah this can be done with Ctrl+Z and a simple temp version control using stack or LIFO structure to save the previous states.
• Add a zoom option.
  - Doable via mouse scrolling.
