Good to hear it. Unfortunately such feature is not available in other app, just in Locus.
We created it for our internal usage almost year ago. Because Locus contains five different internal themes, Peter had to edit every single file due to some small changes, so we created this. Unfortunately MapsForge comes later with own, I think a more complicated solution, which is not supported in Locus yet as you know. Anyway for Locus users, it works quite well I believe.
