This Emacs package lets you see a hierarchy of maildirs in a separate buffer:
mymail@gmail.com
[Gmail]
.Trash [0/25]
.Starred [0/0]
.Spam [0/3]
.Sent Mail [0/4]
.Important [0/21]
.Drafts [0/0]
.All Mail [0/56]
Trash [0/0]
Inbox [2/45]
M-x mu4e-overview displays a buffer with a list of all maildirs. The root
maildir can be set via the variable mu4e-maildir.
The number of unread and total number of emails is displayed next to each
maildir in this format: [UNREAD-COUNT/TOTAL-COUNT]. If UNREAD-COUNT is not
zero, that maildir is highlighted.
Use n and p keys to go to next/previous maildir (or alternatively, tab/backtab). Use [ and ] keys to go to previous/next unread maildir.
When you click on a maildir or type RET when point is on it, mu4e headers view
is displayed, which shows messages only in that maildir. Type C-u RET to
show only unread messages.
The package also provides the function mu4e-overview-gather which returns the
folder hierarchy and asynchronously counts the number of total and unread
counts for each folder. This can be used to build a custom view of the folder
hierarchy. See it's documentation for details.
