Drag boosters from cargo to GUI buttons/slots (F1, F2 etc.)

Heres an idea,
If you got boosters in your current ship cargo, what if it would be possible to drag them into your GUI buttons? This way you can use some shortcuts to apply them, you would see how many you got…

where is the problem to have your inventory open ? oO then you can also see the ammount of boosters Oo

This idea is shitty and you should feel bad
