Great.

Based on that, what would be even more useful still is a way to browse my code from a within the editor itself. Something with say line numbers on some left pane synchronized with the corresponding file section on the right pane.

Some editors already provide a similar feature using line numbers from compilers ; that's usefull to fix syntax errors typically.

Yup, there is some support for editor integration, although it's still up to you to actually glue it into your editor of choice. See the issue below for more discussion.
