NodeBB use virtualDom??

See here after posting a post "geolocation" button in dropdown.
How/where can i enable it? Is this a plugin?

many thanx..

@PitaJ thanx. Fast answer. Many thanx.
Works only for "js" not for "css"!
Can i set "developement" in config.json too? Exist a list for configs-params?

*the actual wiki is really empty. No StructureLayer of Code, Dev-Resource is to small or empty categories ....

Hi,
Anyone have a solution? I need css and js not minified in frontend! Its impossible to devolope design.
In DevMode Files minified too.
Hope anyone can help. Disable this feature hardcoded is a solution too.
Thnx
