I think there should be a way to replace all occurences of a piece of code in a file/page.
For example,
You have a picture that you used multiple times. The picture is outdated and you find a new, better one. Instead of going through all of the images and replacing them manually, you click the new “replace all” button and voila! All of the old images are replaced with the new one!
Having something like this would make coding faster and easier.
