There is the Eastern stands and the monstrocity of a walkway leading across the terminal towards there.
New immigration hall and extended baggage hall with 2 new belts, these of which are actually quite nice.
The western pier has been redesigned to allow inbound passengers access to immigration via the ground floor (instead of ups and downs)
Aside from these, just small cosmetic things here and there. The upstairs extension in departures(above the new baggage area) has not been opened, apparently due to lack of money!
The front of the terminal needs a facelift. Now the roads outside are out of use, with huge blocks since the Glasgow incident, how about some greenery (tree's, flower beds etc!)
