Dell Peripheral Manager - Add On Screen Notification for Fn lock

I have the KB722W1t keyboard and mouse combo. I love the keyboard and how it's compact while still having the media controls. However, I'm a developer and sometimes not knowing whether the function lock is on or off can be an issue. For instance, if I go to replay a song (F5), I could potentially run a SQL server script in SSMS. Or an unwanted refresh of a page when debugging.

Just like the scroll, caps, num lock notifications; it would be great to have a notification of the lock status when switching the function lock.

Thanks!
