Yes, for about a year now, both in the console (alacritty) and vscode, and I think it's great. Granted, I mostly ignore it, which is a good thing.

I frequently change the term emulator font size, and each size oddly changes the "aspect ratio" – for lack of a better term – of both Plex and any other monospace font. I find it weird, but it does sometimes help to have a somewhat narrower variant of Plex, especially for side-by-side terminals.
