[Request] Line numbers in source code panels
Thanks for making such a useful tool! I just used it to find a bug in TypeScript's source map support.
It would be very useful if you could add line numbers to the source code panels. In the linked bug report, I have to tell the developers to CTRL+F for the statement with a missing map.
EDIT: I edited the bug report with a minimal test case, which removed the need for line numbers. Originally, I linked to a much larger document.
Happy someone else suggested this, as I was about to do the same.
It might also be helpful to have column information displayed as you are hovering over a particular mapping in the source/transpiled code. If I share a screenshot with others for a particular mapping, it would be cool if there was a tool-tip to display which mapping (line/col) was being looked at
