SBCHAVEL  It's really nice to be able to see the mailbox by mailbox breakdown.

Clicking on a specific mailbox in the drop-down menu should open that mailbox in Mail.app; likewise, clicking a particular email should open that email in Mail.app. Instead, either action opens up a preview pane that includes all the new emails in a single list.

Checking the Growl preference brings up all the new emails in Growl but each one needs to be closed mechanically rather than close automatically after a fixed time. If you get tens of emails, this can be tedious.

"Set mailboxes" should probably be renamed "Preferences," although that is not entirely accurate either, since the preview of unread emails list is accessed in that window as well.

CLARUSAD  Really very good menubar item ; this is a "killer app" ! Works with Growl. A must have.

JUANCAB  The most recent version (0.6.5) crshes on launch under MacOS 10.5.3. I can't address any earlier version of MailUnreadStatusBar, but the current version doesn't even launch.  
(Version 0.6.5)

GREGR  Still quits immediately after launching. I'm still using 0.46, which is the most recent version that runs.  
(Version 0.6.2)

TUISHIMI  This just does not work for me. Mac OS X 10.5.2 on an Intel iMac. I load my mailboxes with messages, start this thing up (set to check server) click on update... nothing. I try off-and-on for 5 minutes, nothing. I start mail... loads all the messages that this app should have told me were there to be read.

ASDFASD  It simply doesn't work!!!!  
(Version 0.4.6)

DOC RENAUD  At last ! A menu bar that doesn't check only my Inbox maibox, but all the boxes I created.

All other similar apps I tried were useless for me.

Thanks so much !

SIMI CHAVEL  This wonderful little app allows to see not only the number of unread messages in your IN box, but also those in any mailbox to which messages go automatically via your rules. It sits on your menubar, and can show the total number of new messages. Click on the menubar, and you see how many in each of the mailboxes. Preferences allow you to determine which mailboxes it checkes and how often it should do so. Doing without it seems pointless.

Recommended feature: ability to open a new mail message from within the menubar item.

Stability: In the past few updates, the app has begun quitting itself or hanging. But I do not yet have 0.4.5, only 0.4.4 (router downloading problems), so this may have been fixed.

ANONYMOUS  Reference my own previous post...I should have done a bit more troubleshooting before posting. After I deleted the preference file, the app now works....sorry  
(Version 0.4.5)

ANONYMOUS  I just upgradedfrom 0.4.4 to 0.4.5 and now it does not seem to work, although it did start up mail.app when it was not already running
