A lot of screens which have lists on them, like the tenant list screen or the owner list screen or the extra charge list screen etc have all got a new search box which you can use for filtering.  

You can type anything into the search box, and the list will be filtered for any row which contains the thing you typed in any of the columns.  So you could be on the tenant list screen and type part or all of the property code, because the property code is shown on the tenant list screen.  Of you could type part of the tenants first or last names.

This is going to be very helpful for people with long lists such as a lot of tenants or many extra charges.  This is very simple, but I think also for some people very powerful.
