agree for station names - system names should be stable these days if coming from the logs (notwithstanding mrmp's post above)
Actually, now I've come to code it, it doesn't make sense to use the "edit commodity" window to change the system or station names, those fields should probably be read-only. It would be better to use the Rename Station function on the Station tab instead because there's bound to be a bunch of commodities with the same error and you can do them all in one go that way. Maybe I should relabel it as "Rename / Merge Stations", because it's not necessarily obvious that you can use it to merge "Something Dock" and "Something Oock" into a single set of "Something Dock" data.
List of commodity names will appear in the edit commodity window at the next release though, that's coded and working nicely.
