I use the find-in-files feature to search for all occurrences of a function call, then go through them one by one, clicking on the first, deciding whether to edit it or not, then moving to the second, and so on.
Once I finish editing, I want to pick up where I left off, but I lose track of my position.
Having the line number in the search results would make this easier. I could quickly compare it to the editor’s current line number and immediately know where I am.
