I would like to add a new discussion about layout - not the new SEARCH layout.
Instead about the changes which are made to the window when you ADD a new trade - actually hitting the +sign.

When U add a new trade today - your backpack is NOT displayed as U have choosen to sort it. All empty slots are taken away and all items is packed together in a non-ending row. Exactly as the inventory is shown in Steam-profile.

There are reasons why I sort my gears in my TF2 backpack - I gather them together in groups which I shall sale and keep, I sort them to be sure I follow the rules at tf2outpost:
For example - IF U display the same item in two trades at the same time - U will be banned for a day (Been there - done that)
Now with the 'packed' version of my BP there is a great risk for unintended missbehave.

I started by fileing this as a BUG under another section here at forum - but realised it is a feature! Maybe it is something that shall help use from mobile devises - But I do not see how it makes it easier. (the new devided scrollwindow at SEARCH and ADD - I believe is introduced for that reason)

Conclusion: I dislike the packing of my BP - I want it to be shown exactly as I sorted it - with empty slots! At least there should be a setting wheer I choose to display my BP in 'packed' or 'real' version.

Now - May I hear your opinion!
