Currently you cannot tell which column the 'selected' item is in: for example in the screen shown on attached image, you cannot tell by looking which item will move if you hit 'up arrow' on keyboard (it is the second column - projects - in this case).
Would be better if the marker that has focus was highlighted somehow.
Traditionally this has been done by changing the colour of the highlight.
