I don't use the mail ticker, but that will do it. The Bat! Has Virtual and Common Virtual folders. I have one set up to look at all the trash folder in every account. You can easily set one up to look at all inboxes and show only unread messages if you so wish. There is also a tab on the lower left called "unread" that will show you all accounts that have unread messages in them and you can from there go to them directly. I virtual folder will always reply with the correct account credentials. I use a common inbox virtual folder which has an unread tab for filtering, but you could easily make it only show unreads CAVEAT: If you add an account after creating the VF, you will have to manually add it into what the folder watches, but that can be done after you create the account by selecting "WATCHED BY" in the account folder
Play with it a bit and you will see how powerful and flexible this is

Any option that relies on Read and Unread is hokey-dokey. I have lots of forum mail where I do not care much whether it is read or not.

It would be good for TheBat! to try to emulate the Eudora Filter Report. Fr om a programming standpoint it should be fairly straightforward. since it is simply a type of online log.  What it does for the user is show what is happening on the Inbox, or on a specific manual filter.  It is not critical, and not everyone will use it, but it is an excellent feature.

As a simple example, you can run a download of mail, look at wh ere everything went, and quickly tell if your filters sent mail to a place that you did not expect for download.
