Firstly, let me say that the addition of "Admin Notes" is a wonderful addition.  It really does help admin(s) to keep notes on a particular profile in the place they belong, which is as part of the profile.

My suggestion is that they should allow the use of keyboard-only entry.  When I am using the keyboard to enter a note (see attachment), and click the tab key to go to the "Add" button, the note which I have just carefully typed disappeared!  I am forced to use the mouse to click on the "Add" button.  Please make it possible that I can use the normal keyboard keys.
