I'll only answer Danny's comment:
" If it ain't broke then don't try to fix it "
This forum has effectively, been broken for years and people have been complaining for years:
It's hard to use on phones.
It's hard to use on apple devices.
The editor is hard to use and non-standard.
Putting up gallery photos and managing them is difficult
You can't quote more than one post
Selective posting is hard
Embedding links is difficult and different for different types of content.
Some content wrecks the layout
Messaging isn't very flexible
The search is next to useless
Avatars are hard to use
Managing your profile is difficult.
No reaction mechanism
Now the key thing is we get weekly, if not daily, complaints and requests for assistance with things on this list.
If that isn't 'broken' what is?
There will be complaints and a period of adjustment, but I very much doubt that after a month the complaints will be anything like those that we have had.
