I've never had X forwarding work well enough to actually be usable, and last time I checked NX was still a massive (/non-free) pain to setup.

Besides, I already have a workflow that works perfectly fine, is headless as I prefer, works with mitmproxy, etc.

Also, I installed Fiddler from AUR again this afternoon and it just looked awful. The settings menus were unreadable, for example.
