Tiny MCE question

[pwired]

I still have a few old websites with Tiny MCE inside processwire. When I edit body content I sometimes prefer to use the html source editor e.g. to edit a html table. However all html code show up inside the source editor wrapped over the editor. This makes code difficult to read. How can I configure Tiny MCE so that html code inside the source editor show up as lines of code stacked vertically with line breaks like in a code editor ?

So far I found it:

wire/modules/Inputfields/InputfieldTinyMCE/InputfieldTinyMCE.js

apply_source_formatting: true,

Code inside Tiny MCE html source editor no longer looks like a blob of code

but lined up vertically.
