New built-in functions for item lists

1

Hello!
I'd like to propose new functions for item lists:

1) freezing view of the selected (first 'n') columns -> following the thread: https://community.webcon.com/forum/thread/2603?page=1#m2610;

2) enabling (showing) / disabling (hiding) rows in the previously initialized item list -> business case: in the step after initialization we disable (or hide) all the rows except for the selected ones (preferably); after the data was entered to the required columns of a current row, that row is being disabled, while the next one is being enabled (or shown & enabled).
