See the release notes. Those buttons are now on the header panel of each message. You can put them back on the top toolbar. (I have.) Also, get the "compactheader" extension to control the space used by the message header panel.

Never mind. I found the (very tiny, unlabelled) arrows next to where it read "Smart Folders". Clicking those changes the view to "Unread Folders", "Recent Folders", etc. Eventually, I got it back to "All Folders". That was a bit disturbing, to say the least. Another thing I noticed is that the "reply", "delete", "junk" buttons have gone AWOL from the toolbar. That's easy enough to fix but couldn't it have updated without making the user go back in and add those again?

Hi, At the top of your mail folders, you have two little arrows. Using them allows you to change the look of your accounts and permit you to go back to an inbox per account

> And, by the way, does TB 3b4 work fine with the IMAP protocol? >  Summary   Imap is fine.   Turn of global indexing.   Choose which folders you want tb to store for itself - it stores them all by default.  Details.  Imap works yes - tho I have heard of some with problems - I have found there seem to be some nasty quirks/bugs associated with GLODA - I turn it off on all my computers (Preferences->Advances->Enable Global Search).  I have found the indexing either messes up or never completes (after 11 hours on x64 anyway) - it slows things down and I have no interest in co-mingling my searches across email accounts. - so the design idea is just silly IMHO. (I am not a fan of smart folders for similar reasons).  Also, GLODA demands a local (thunderbird stored mbox format ugh) copy of all mail. You will need to go through carefully and deslect any folders (one by one sadly) you dont want duplicate copies stored by thunderbird.  Since I keep copies of whatever I want on a local imap server for my local storage (so I am indifferent to mail client) I have zero interest in yet another copy of all my emails and saved emails stored in a slow, bad, buggy format which requires me to keep pressing compact every other day. While my laptop drive is large, another 5 GiB of duplicate copies is silly as well.  I have also switched to using the 32 bit version on my x86_64 installs - in fact I am now using the nightly build of 3.0pre from mozilla.org. Tho I am not 100% convinced there are 64 bit problems or not - and the TB devs dont seem sure if there are or are not either.
