Woke up to this, early this morning 
when it appeared to be just drawing its first breaths.
Persevered for an hour or two then went for a walk for an hour or two to clear my head.
It appears to be working reasonably well now but is certainly slower than the old system.
After lots of fiddling at the margins I've now got it set up reasonably well..............I think........ but we'll see !
It reminds me of such as Ebays recent re-hash of their purchase and selling pages which look a bit fancier, however on the old pages I can see at a glance all the info I need on one page, but to see the same on the new pages I have to click back and forth thereby wasting time.
Change for change sake I wonder ?
After reading online about both BT and Ebay it appears that both companies simply change what they want without asking customers, or customers having asked for the changes, correct me if I'm wrong. 
There is mention in previous posts about gathering email more efficiently via other sources, such as Thunderbird, which I use, but that's not the point, I pay for my BT email accounts and expect BT to provide a superior service and experience, to such freeware as Thunderbird.
Two things in closing:
1) Wouldn't it have been nice if BT sent all email accounts an email month giving or so's notice of the impending new system, they can certainly send out plenty of emails to try to ell stuff !
2) Isn't Adblock plus great, though it gets rid of the ads, there is still the lump of wasted page still there, I don't know about anyone else, but I buy what I need, not what an say's I may need.
