I love this font so much. Actually I use the nerdfonted version "Caskaydia". It just sucks that it does not have italics. But just the last month I was trying out every other font under the sun (with ligatures), including checking out some commercial ones, but none of these is so damn readable while still being rather dense with the perfect weight and expressiveness than Cascadia.

It makes the code so much prettier. However I am extremely open to alternatives that look similar but have italics.
