counter/noop, incr counter, clear counter, while (), and for each [i v] in  hidden blocks!
Look at those lost blocks I found by hacking!
Most people never seen the counter blocks before, as I still use them first and I like them. The While loop C block is usually a repeat until not C block. The For Each [X] in  loop C block loops using a variable, but I am unable to chose any of the variables of the dropdown right now, still.
I found one of the block names to add from: http://wiki.scratch.mit.edu/wiki/Scratch_File_Format_(2.0)/Block_Selectors
