JRPAR  I understand your point about Spaces, but I can't seem to get Spaces to work for me. I don't know if it's because I like all of my applications at hand or if it's because I haven't really been able to figure out how Spaces benefits me. Probably the latter, and that's probably due to some deficiency in my character:-)

Meanwhile, MiniMail and I co-exist nicely for whatever reason. And I may be too set in my ways to change.

Excellent application, and build 67 is available now. Much prefer it to the apps that bring up floating, semi-transparent windows onto your screen. MiniMail is unobtrusive, but available at a glance when needed. Developer is responsive, which is always a good thing.

Two features that I would like to see considered:

1) Capability in the actions menu to select which rule to apply to new messages that don't already meet rule parameters (sometimes I can't remember which rules I have active), i.e. if I want to tag it, etc.

2) An indication of some type to let me know if I had multiple new emails by the same sender, same subject, perhaps designated by color. That way I would know to scroll through to find related emails--helpful when working on a project or issue that's changing quickly throughout the day.

As I said, though, MiniMail is a great idea, well executed by OliveToast Software. (1/12/2008, Version: 1.1 build66)
