yeah it's a resolution issue
and there isnt really 1 file to change to make everything shift to the left
the scout cards are intertwined into 3 places and when you make changes to fit 1 screen it will most likely look strange on the other screens
If i was you, i would probably try and make the inbox "left side" less wide and hope the attributes would fall into place.. i can't remember where thats done, but probably in the inbox panel.xml
try and change line 53
<attachment_group class="horizontal_arrange" horizontal_layout="-3, 1, -9" horizontal_offset="0" horizontal_gap="0" vertical_inset="0"/>
change -9 to -10 and see if anything changed
