Display duration in Beacon Fuel Tooltip

Here’s a REALLY basic and simple suggestion regarding the tooltip of beacon fuel.
Why not show how long a beacon fuel item lasts?

I didn’t do it myself, but it could also indicate that beacon fuels are not additive, meaning you can’t put 4 basic beacon fuel items and expect them to give you as much time as 1 greater beacon fuel item.
I think that should be reflected in the tooltip. It did trick me when I started playing a year ago.
