Dynamic List from other Sheets - Auto adjustment if row/column inserted in others sheets

To refer to cell in row 3 column B of a dynamic sheet name in B2, why not? (No helper, ofcourse):

=INDIRECT("'"&$B$2&"'!$B"&ROW(3:3))

To avoid "Zero" from blank cell, try:

=IF(INDIRECT("'"&$B$2&"'!$B"&ROW(3:3))=0,"",INDIRECT("'"&$B$2&"'!$B"&ROW(3:3)))

Drag down as far as probably need.
