Hi, the Elm Compiler Toolwindow actually enables navigating (forward&previous) to the exact locations.
The error reports that are linked to each location are something I currently work on, so that the nice messages from the Elm compiler and elm-review are displayed better and ideally respecting the IJ appearance theme (dark or light).
When I am done, I can try to publish the plugin as an installable ZIP… maybe on Github, we’ll see.
Thanks for the feedback!
