I haven't seen it from my desktop, yet. I have only a vague idea of what is involved with this sort of switch-over; but that's enough for me to not cast a hasty judgement.
I saw some features I didn't care for, and dug around until I figured out how to disable them (or reduce access to the point of reaching the same result). I also turned off just about all of the notifications (especially those with a social media flavor).
Luckily, I generally start my browsing with New Posts, then check specific areas of I have the time & desire. It's easy enough to jump into the Exchange from new posts; so that will eliminate a lot of the scrolling... and, hopefully, moving things into broader categories will help ease navigation for when I do want to view a specific subforum.
If, after the dust settles & I get a better feel for the new setup, I still don't care for it... well, spending less time online wouldn't be such a bad thing, lol; and my finances will probably be thankful.
