Mail Hub app to work with Mac OSX Mail

I've been using MailHub by Dervish Software over the past several weeks and really like it, and thought I'd suggest it to others.  It's an add-on to OS X's Mail which allows you to create, send, file and organize your many emails into folders easily.  You can set up keystrokes to do it automatically within the application, you can click on buttons, almost any way to accomplish the task.  Plus if  you want to Send an email and delete it [save to the trash] you can do that easily.  That's nice for some of those useless but necessary email messages.  There are other features, tho I am so far focusing on those.  It's worth a try [30 day free trial]  And when I contacted the company, I received a prompt response.
