Optionally add vertical motion to elements in Columns/Rows/Boxes transitions. Accepts three possible formats denoting either random, cycles or direction based movement. 1) Random: {min,max} Applies a random amount of movement within a specified range. E.g, {-45,45} to slide in by an amount between -45{bbackup_94402fb9ba80f392e0976ece85f92b2b876bfcaed8d83250cc06083f7139c7d9} and 45{bbackup_94402fb9ba80f392e0976ece85f92b2b876bfcaed8d83250cc06083f7139c7d9} of the element's height. 2) Cycles: [val,val,val] Cycles through applying specified movement amounts sequentially from one element to the next, in the order determined by the 'Flow' setting. E.g. [-10,10,25] will apply a -10{bbackup_94402fb9ba80f392e0976ece85f92b2b876bfcaed8d83250cc06083f7139c7d9} motion to the first element, 10{bbackup_94402fb9ba80f392e0976ece85f92b2b876bfcaed8d83250cc06083f7139c7d9} to the next, then 25{bbackup_94402fb9ba80f392e0976ece85f92b2b876bfcaed8d83250cc06083f7139c7d9}, then the sequence repeats. 3) Direction Based: (val) e.g. (45) to add 45{bbackup_94402fb9ba80f392e0976ece85f92b2b876bfcaed8d83250cc06083f7139c7d9} motion when going to the next slide, and -45{bbackup_94402fb9ba80f392e0976ece85f92b2b876bfcaed8d83250cc06083f7139c7d9} when going to the previous slide.
