DJI, how about adding a status light quick cheat sheet to the DJI Go app.  
I don’t always remember the light patterns and a simple screen in the menu would be great.

Hi, thanks for the inquiry. The description of the status LED light indicator for the DJI Spark can be found on our manuals. You may also check the screenshot below for your reference. No worries, we will forward your suggestion to our designated department for attention. Thank you for understanding.
