Not sure why this got closed.

Oh hey only incidentally related, but have you seen all the options that have been added lately around fonts in the Windows Terminal Preview builds?

At this rate it might not be too long before it unseats Konsole as my favorite OOB (more or less) graphical environment terminal emulator app. 👌 It's already at the point I miss some things from WT whenever I'm in bash (or pwsh or zsh or sh or whatever) on Konsole on Linux.

Although... pwsh does get some of it back and I'm actually not entirely sure why I haven't made push my default text mode login shell yet. 🤔

Anyway... Nice additions, but it does make me wonder if we're going to end up having to deal with both WT and the remote shell environment fighting for dominance/control of what the user ultimately sees, likely overriding what we are trying to give them but not letting us know about it. Not sure. Any thoughts on that @tig ?
