Feature request: Create a timer showing how long a user has been editing a specific file

[dheista]

Just out of curiosity, I'd love to know how many hours it takes me (or someone else) to edit a specific timeline file. Not sure how you would measure time "editing" because I often will keep LSG open when I close the lid of the Mac, so you would have to measure keystrokes or mouse movements or something to indicate the user is actively changing a timeline, and only time those behaviors.
