Italic fonts are removed now. The theme looks awesome.

Perfect, thank you so much

Thanks bro!

Thanks you!

I saw that video. I am slightly confused as that video was targeting color customization. How can I change the below for font style, not color customization?

storage.type.js
"fontStyle": "italic" 

what extension is that i'd really love to get it

I didn't realize the article I linked is no more.
Its not an extension. Open the Command palette (Ctrl-Shift-p by default) and search for "Developer: Inspect Editor Tokens and Scopes".

add more

"keyword.control.flow.ts",
