The best part about this tool has been its ability for our team at work, especially in regards with identifying patterns using data analysis which can then be used as reference points within other tools we use more regularly such us Excel etc., This saves so much time when it comes down analyzing large files/data sets through multiple programs without losing valuable references! Nothing yet!! We have not seen anything wrong but I am sure there will come along once you are able start doing things faster than before since all those repetitive tasks were done by software now they take less amount ooohh mannnn.
