When you click on the "Center on my location" button, the map is centered on my current location and the bluedot_retina icon is displayed.
When I hover the mouse on this icon, I get the title "My location".
I wanted to translate this title. No way. When I look at your code (show.view.js), I can see this title is... hardcoded.
I try to modify the code to add something like this.translate.('TO_TRANSLATE') or Joomla.JText_('TO_TRANSLATE'). But this doesn't work !!!
Thanks for help.
