Huh - that space has been around for 3+ months (since revision 1.3):

http://cvs.horde.org/annotate.php/imp/templates/thread/thread.html?rev=1.7#46



I personally prefer the space between the messages because, to me, it 
helps me distinguish between the messages easier.  But whatever others 
think is better is fine by me.



I'm going to go ahead and close this ticket as further usage over 5 or 
so days now indicates the code is working well - further 
bug/enhancement reports can be handled via dev@ or new tickets.

Looks great! Is it by intention that there is now an empty space 
between all messages? IIRC these haven't been there before.

Initial implementation finished in HEAD.

Bounty added: http://www.horde.org/bounties/details.php#imp_multimessage

Had to do some reasearch on horde.org, but finally worked out what 
HEAD means, and yes, of course that's the queue version I should have 
filed it on to begin with! Newbie moi. (may be advisable to put a 
little tip on http://bugs.horde.org/ticket/create.php about queue 
versions ...)

If at all, this will be done in HEAD only.

ON low bandwidth links it's often a pain to view mesages one by one. 
It is easier to select the messages you want to read (usually all 
unread ones) and click one button to have a page presented which shows 
all the selected messages one after the other. I once patched aeromail 
locally to do this. An enormous benefit.



When the link is slow, you do one page load and come back when its 
done then read your mails. It takes a little coding to ensure that all 
the links relevant to each message maintain that functionality, but 
otherwise you just repeat the standard message view over and over.
