I patched someone else's program which was known for being slower when it's used for a longer time. It was iterating over items in its window just to reach the last element, the more items the slower, it became snappy when i taught it to keep a pointer to the last element.
Not mind blowing, I know, but it was a popular program and this made life better for many people.
