I was thinking that somekind of calendar would be useful. I mean a page where you can visually see upcoming events for month or two e.g when new/used planes are arriving, C&D maintenances, endings of marketing campaigns etc.
I know that you can check all these things in various pages, but it could help people who aren't spending so much time in here. And maybe it could be helpful for bigger companies.
And maybe you could choose what events are shown in calendar also.
