We are sorting by *label*, so as far as I can tell the mailboxes are 
sorted properly.  Maybe the issue you are describing is that we are 
thereafter *viewing* by the abbreviated label.

Thus these mailboxes:

IN.Zsent
Sent

Would be viewed in this order in dimp:

Zsent
Sent

Maybe sorting by abbrev_label is the more appropriate thing to do...

This is not exactly the same issue, but might be related: the 
sent-mail drop down in the compose window is a bit "confused" at the 
moment. It doesn't display the translated labels, but it puts the 
special folders where they would be *if* they were translated.

Oh, and one thing I noticed: even though the "normal" sent mail 
folders are correctly sorted now, the translated folder is not. In my 
case it happens to be the first in the list, so this might be 
intended. Just checking.

I think this behavior makes more sense though than using the default 
identity's sent-mail folder for translation. Rationale: by default all 
identities use the sent mail folder from the prefs. If an identity has 
a different sent mail folder, this one was explicitly 
picked/created/renamed by the user. Chances are high that he used a 
certain name to distinct it from the default sent mail folder. That's 
why it should not use the default translated label.

Fixed.

Bug #10683: Sort multiple special mailboxes in a single category by

Depends what you consider broken. For me the only brokenness is the 
sent mail folder labels not being sorted alphabetically.

And now I am even more confused.  Because I can't reproduce.  I only 
ever see one 'Sent' mailbox - all others are displayed with their 
display names.

I did notice one issue in the label code - we were not loading the 
default identity's sent-mail mailbox but rather the sent-mail mailbox 
defined by prefs.php by default.  So this has been changed; not sure 
if this fixes things (doesn't change any behavior for me).

Now I am just confused.  Apparently, somewhere in the last few months, 
my identities switch to saving all sent messages to a single mailbox.   
I changed my Horde identity to its sent-mail mailbox... and it 
correctly displays the name of the mailbox, not 'Sent'.

But this is also a first-level mailbox.  So it seems the issue is that 
all mailboxes underneath a special mailbox are labeled as a special 
mailbox.  Whatever I think about the sent-mailbox labeling, this is 
simply flat-out wrong and needs to be fixed.

No thanks, that's awful usability.
It not less intuitive than having a bunch (7 in my case) of sent mail 
folders all with the same name.
FWIW the sent mail folder that matches the default sent mail folder 
name (Sent) is still displayed translated correctly. And I never found 
it confusing that the non-default sent mail folders are displayed by 
their real names. I find this pretty logical actually.

It may be caused by the fact that they are all second-level folders. 
But again: this is the desired behavior, and I do *not* want seven 
"Sent" folders in my special folders section.

You have to know the mailbox name (which you can get by hovering over 
the Sent mail).

Displaying the mailbox name in the special folders would be 
inconsistent UI (your sent-mail mailbox no longer displays as Sent 
simply because you've defined more than 1?  that is not intuitive).

I could see adding a "label" option to the sent-mail setting in an 
identity.  But by default, the mailboxes should be labeled Sent (it 
could be argued that their should be a single virtual Sent mailbox).
This is the way it's always worked for me.  I have 2 different sent 
mailboxes (Sent and sent-mail) - they both have always displayed as 
Sent.

Because how do you want to distinguish them if they all have the same label?
No, it never worked (for me) that way at any time. And I doubt for 
anyone else because different sent-mail folders would be unusable 
otherwise (see above).

Why not?  They are all sent-mail folders.

Plus, this is the way they have always been displayed.

Now I am confused. There are individual sent-mail folders for each 
identity and of course they are not all displayed as "Sent". :)

Confused by this - how would we sort by label?  All sent-mail 
mailboxes should be displayed with "Sent" (or its translated 
equivalent) - sorting won't change that order.

Much better, but the sent-mail folders are now sorted by their value, 
not by their label.

Although nobody ever complain over here (myself included), I agree with Jan.
Over here in French, special folders appear in this order :
Inbox
Drafts
Trash
Sent
Spam

I don't mind about the *exact* order, this was just the order that 
made most sense to me intuitively.

Also, for the record, this has never previously worked the way you 
request since Spam used to appear before Sent (again, at least in 
English).

Lucky you :)

For the record... this *is* the way it is sorted currently (at least 
in English :) ).

I think this worked already earlier. It makes more sense to me to sort 
special folders in the dynamic view not alphabetically (at least not 
outside "groups" of folders), but by importance, i.e.
Inbox
Drafts
Sent (all sent-mail folders alphabetically sorted)
Spam
Trash
