Suppose you have 2 customers that are named 'Van Terp A' and 'Van Terp B'. When users enter the value 'Van Terp' in a 'Customer No.' / 'Customer Name' field (e.g. on the sales order / sales invoice), the customer dropdown list is shown after 1-2 secondS, so (s)he aware of multiple results and can select the correct one. All Ok, as long as the user is patient to wait for the dropdown to appear ...

Since it concerns a Power user (coming from NAV Classic) that is actually used to input complete documents in seconds, (s)he doesn't wait 1+ seconds for the dropdown to occur and presses ENTER / TAB to continue to the next field. This results in BC always taking the first valid value instead. They need to have patience for the dropdown list to load first, then select the correct customer and enter / TAB. This takes approx. 1 - 2 secs to load, which is too long for these users.

Can this be enhanced so the dropdown is at least shown in case multiple records apply / results are returned by the search query?

We used to create our own Search function all over our addon to provide this behavior, but it would be far more better if MS / BC could provide better native support.
