slot management page

[groundbum2]

I'd love a slot management page, with different tabs

tab 1 - slots purchased,not flown - from here for 1 or mutiple slots, at both end or one end of the route I could release the slot and thus stop the annoying emails

tab 2 - slots flown, not yet purchased - from here for 1 or multiple slots I would buy buy both or one end of the route. It should indicate how much the slot should cost and it's availability or not

tab 3 - slots that I own by hour by day by airport, so I can find a slot to reallocate to another more profitable route. No actions from here, other than to to drill down to see which routes are using slots in that hour/airport/day.
