Please modify the add-on so that we are able to drag entire FOLDERS of emails
via the QuickFolder bookmarks, as well as individual emails within FOLDERS.

I have many folders of subfolders, and each subfolder contains numerous email
messages.  I wish to easily move these subfolders from one mail account all the
way down to the LOCAL FOLDERS for historical/backup/reference purposes.

Currently the only way to move the entire subfolder to a different location
(i.e., LOCAL FOLDERS for example) is to drag the folder from its current
location to the new location, which often means trying to drag the folder over
many screen pages.

It is highly desirable to be able to drag the selected subfolder to the
QuickFolders bookmark for the LOCAL FOLDERS and then right-click to select the
appropriate location within LOCAL FOLDERS.

The question is, how useful will it be to the majority of users? It would be
great to get some more QuickFolders user opinions on this...

 Having said that, the most logical way to implement this would be by dragging
a folder (or folder menu item) from the QuickFolders toolbar (or Current Folder
bar) to the folder tree (left hand side), as it would allow you to do your
scrolling (to the bottom, or wherever you need to go) _before_ the drag and
drop operation. Also there is currently no function assigned to a QF drag into
the Folder tree.

Having said this, it might be quite hard to implement, and I am not sure
whether many users would benefit (or even find the feature). So I have to weigh
your personal benefit against slightly complicating the Add-On and probably
spending quite a big portion of my free time on this feature. Which wouldn't be
bad if hadn't planned other features such as customized Icon support, easier
Categorizing and simplification of the style sheets. 

By the way I have implemented your other request (Add hot key to invoke
QuickFolders command menu) as it wasn't overly complicated to implement - a few
hours debugging and a few emails to the moz.dev.ext newsgroup.

Any additional thoughts?

Test Version with Folder Move

Here is a test version (not fully localized), which supports MOVING a folder by
dragging it from the folder tree (left hand side) to a QF tab. You have to hold
down SHIFT to do this.

It doesn't yet support dragging into the subfolder popups, but it is planned. 

Also I haven't tested it very strongly (e.g. I haven't tried "illegal" stuff
like moving news-groups folders or moving from an IMAP server, so be careful).
Best to run MozBackup before testing these features.

In theory, "illegal moves" should be caught by the API function I am using - it
should throw an error and display a message that it can't be done.

uses nsIMsgCopyService.CopyFolders

The test version seems to only work in Thunderbird (not SeaMonkey / Postbox). I
think there is some bug in the drag+drop implementation on the other
applications causing the keyboard states not to be reported on the right-click
event... needs further investigation.

Aloha, Axel. Apologies for being so long in getting back to you, but other
business kept me occupied. :(

Thank you so much for implementing this feature! I had assumed you didn't have
the time, but then you did it! I really appreciate it and have already put it
to very good use. ;)

There are only 2 glitches I see with it, which you probably never even
encountered. 

1.  If the bookmarked folder you are trying to move a folder to (the
"destination") contains more "contents" (subfolders and/or files) than will
display on the height of your screen, you are unable to effect the move. That
is because the "focus point" for the "destination" is right on top of itself --
so every time I try to do the move, the "contents" list totally hides
"destination" bookmark. You probably have a better idea, but an option that
would make it simple (for me, of course, not necessarily for you) is to add the
"destination" bookmark  folder itself at the top of the "contents" list so that
I could still select the "destination" bookmark rather than a subfolder.  I
hope I made all of that understandable; if not, please let me know. I will also
email a screen capture that should make it more obvious. ;)

2. It is hard to get the move "selected". I try to click right on the bookmark
name, but it often takes 2-3 tries beore it "takes."

Thanks much, Sheron

yes, do that :-) just attach it to this bug. There is a general problem with
dragging / handling long menus, they shouldn't really cover the target object,
but that is a Thunderbird bug. Nothing I can do about that.

Try to left-click instead.
