When the checkout table is updated by renewing or checking in a selected item, the page does not refresh. 
This leaves the message "Patron has ITEMS OVERDUE" in red at the top right of the screen when actually no items are overdue.
If the item is checked in, it leave the item visible in the Checked Out items table - with the message "checked in"

Some of this may be an intended feature, so - comments welcome!

My request is that a modification is made so that at least the ITEMS OVERDUE message is removed once the renewals are completed.
I think in earlier versions the whole page was refreshed - checked in items disappeared, and the Items Overdue message disappeared once the "Renew or check in selected items" button was clicked.
Now that the table is Ajaxed, simply refreshing the entire page might have possible unforeseen consequences that developers may need to address.

Note that you can see this effect also - if a barcode is typed into the "Enter item barcode" box, but check out is not completed, and then you renew or check-in an item in the checkout table, the barcode remains in the box.
