In VPL1, touching a block on the side panels adds it to an the first row having no block of the corresponding type (event/action). This is convenient because it allows to very easily add a program, and was critical in VPL1 as drag and drop was broken with some old graphic drivers on Windows.
In VPL2, this is not implemented (yet). On mobile devices, drag and drop is very natural and there is no graphic bug. The question of whether to implement this feature in VPL2 is open:
(+) it would provide an even simple way than drag and drop to add a block.
(+) it would be similar than in VPL1
(-) it provides two mechanisms to make the same thing
(-) it might prevent people to discover the drag and drop
