> How do you view HTML/Code/JSONs in other applications?

Not GP, but I'll be forever thankful to have been able to make my career focused on embedded software.

In my line of work there's nothing to view because there's no visual component at all. If my user(s) "see" the results of my work, then it means I've catastrophically fucked up.

I spend 90% of my time working in vim within XTerm.

The closest I get to UI/UX is a UART debugging interface.
