Hi,
I am new to lighting app and TV application development.
After create a new LightningJS App, the below info is shown bottom right corner in browser:
APP - v 1.0.0
SDK - v 4.8.1
However, I want to delete these info. Please help me how to proceed with this.
Hi Gary, welcome to Lightning 
You are referring to our Version Label plugin.
You can learn more about this plugin (and how to disable it) in the Lightning-SDK docs
Hi Michael,
thank you very much!
Hi Gary,
on top of this, you may want other tools / settings enabled / disabled in your application and the documentation for that is here: Settings - Documentation
