Indicator for updates available

Suggestion, perhaps for another column in my Library window: what if you added a column, an icon, or something to indicate that (1) a volume or (2) a series has been updated?
For instance, I normally don't pay a lot of attention to pre-pub. notices in my home page of Logos 5, but today I did, and noticed that a commentary series I have has 6 volumes now in pre-pub. And when I clicked to the page at your site, I noticed that my collection lacks several books from a previous update--which apparently was in the last 12 months, but I hadn't noticed (or I would have gotten them).
Just wondering, then, if anytime I use a book or a series of books, there might be a discreet indication that an update is available. Perhaps this could even be an indication that could be turned off by those who don't want to add to their collection at this time.
