I really appreciate the performance boost. We have a quite complicated sheet before and adding 20 more rows at a time is annoying. Yes I know there are ways to add 20+ but the default low limit shows how slow it is. With this new system, Google is confident enough to allow user to add 1000 rows at a time (default value). Scrolling seems to be very smooth too. Overall a great upgrade!
