When using Forms in Windows; if a form has a table that is pre-filled from a lookup it may contain multiple lines (for example a stock list).  The user can search for an item in the table using F3.  This is a Windows function and search item will display even though it is off the screen.

When using Offline Forms on a mobile device there is no search function.  If a table is long and extends well beyond the screen the user must scroll down to find an item.  It is more likely that tables will extend off the screen on small mobile devices.

A search function would be a good feature for Forms Offline.
