Drag & Select is there, you have only to click on the Left-Border of the grid to do it.
Pressing the keyboard too, but this work with ALL Columns, not only with the title like the old. So, to search by keyboard a title you have first to select the cell that has the title inside.
But drag & select has some issues with grid colors i think; the selection colors does not appear on "SEEN" movies. =( BUT, it works as you said too... So I'm gonna remove those from the topic.
