As a developer, when editing page it is difficult to navigate and find that exact line of code that is needed, because there is just too many lines (usually 1500-2000+ lines) so it is just Nightmare to keep on finding exact line, because first you have to open the script of page you are editing in the "Page Source", then find what you are looking for in "Elements" and remember that part, then go back to "Page Source" and start searching by eyes, because "Find on page" doesn't work often.
