Ah, so you mean somewhere on the WME display you'd have a button to open up OSMC/OSOD at the same co-ords... In theory it's possible - I haven't delved into the WME code yet to see how easy it'd be to extract the location, but if getting that isn't a complete ballache then it'd be trivial to pass that across to OSMC using its internal permalink feature or to OSOD via my script.
Meanwhile...
...now properly waits for the default OS map to load before relocating, and plays nicely with Chrome again.
Meanwhile...
