When adding a trade item to the trade totem, an addional info text appears. This text disappears very quickly, before I can read all lines. I had to take a screenshot to be able to read everything.

I am not sure if this is on my PC only (due to a good internet connection) or if others have the same problem - or if I am simply too old to read quickly enough. *cough*

My suggestion is to either increase the display time of this message or to use the empty space on the trade window for displaying this text permanently (I marked the space which I mean in yellow on the screenshot).
