Marketshop Window Editing

Hi,

I wanted to ask if it is possible to edit the marketshop or the tradewindow that it displays more then just 6 items in 1 window?
If yes has anyone done that allready?

Would be nice ;

i think u can do that... ya u can, gotta remodel or w/e and change the design and layout of the thing... but again its only clientsided...
