improve search function

[tommer2]

at the top right, there is a search box.
the current search function (in that box) searches down the list and highlights the first row found.
would be great if the search function would be improved :
- continue searching from the top of the list, when the search function reaches the end of the list
- when the search function highlights a row, allow the user to search the next row, e.g. by tapping the search-icon/magnifying glass in the search box or by pressing the enter-key on the keyboard.
