        <pre>When switching between writing and debugging minified JavaScript, it's really annoying that breakpoints are only specified by file:line:column, since almost any edit to the source will mess up line positions.

It would be great if we could think up a better way to port breakpoints between similar versions of the same script. For example, breakpoints could additionally save local context (like a traditional diff/patch) and try to relocate the line using that context if the original line position has different content.</pre>
