Option to indent output with real tabs
Ace editor seems to support it. It'd be good to have a checkbox on the Configure indentation dialogue box to control use of real, semantic tabs in code view/prettification.
Thanks for your suggestion, makes sense.
This is actually really simple to implement as JSON.stringify accepts a string or number as the third parameter. You'll just need to change the couple of places where you check if it's a number to allowing a string through, too.
However, this will need to translate to multiple options on the ACE editor
This is done. If I go to Settings > Configure editor > Indentation and set the type to Tabs, I get real tabs when formatting, saving & copying.
