It’s a timer that records how long you have the file open.
I was curious if it showed how long you were actually doing something in Blender, it does not.
I would still say that you need to redo the layout, it looks way to complicated for something this easy. having dropdowns with a gazillion icons just doesnt make sence to something this simple.
Have a look at this plugin for chrome that i use dayly, it needs to be more in this direction.
Man if you can send that data to asana to keep tracking of how long it took to work on some specific scene, that would be perfect for time management!!!
