Display Subfolders in tree structure (like on thunderbird for desktop)

[Wumm]

Please add the option to display subfolders in a collapsable tree structure like on the desktop:

inbox
    subfolder1
    subfolder2
    ...

instead of displaying all folder paths in a list like it is currently done:

inbox
inbox/subfolder1
inbox/subfolder2
...

This would add greatly to the ease of use and simplicity of the ui.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Oh, Yes!  It's so darned irritating as it is.  It would be even better if we could collapse them and just see Inbox unless we tap it.

I support this 100%. I had hoped so much TB for A would change the horrible flat structure in K9, really the only thing I disliked in K9. What a disappointment for it to be still there.

Yes, please. UPVOTE 😄

I have many folders, it is very awkward and tedious to use without a collapsible folder tree.
