In the Library grid view, the subject text is often very long and it's hard to arrange your columns in such a way that you can read all of it. For creating Collections it's often useful to be able to see what kind of subjects are used for certain books. And anyway, you'd have to readjust all your colums afterwards so you could read entire titles, which would be a pain.
Currently, if you hover the mouse over any column where text is truncated because it's too long, a popup comes up showing you the entire text. This does not work for the subject column. Please make it work.
