There should be a little caution here as Blender already has
specifically set up the UI expectations as a mental model.

If we move a Cube mesh on frame 24, we lose the position on the previous frames.

To this end, it would likely be good practice to follow the model
already in place, otherwise we are running the risk of turning Blender
into a nasty monster with expectations within the interface.

That said, we also need a method do solve the above situation. Would
the Auto Key function be a logical thing to use here?

I'm with Sergey on this one. I think the numerical values are pretty useful.

I think the design choices Sergey has made to include numerical values
here fit within the established paradigm of Blender well too. Nothing
lost for those that want to stick to the purely graphical elements,
and a good deal of high grade granularity for those that require it.

Great work folks. Let's be very careful about the UI decisions.
