I'm still trying to like K-9 Mail, but I'm just not seeing it. I much prefer the display on the stock email app where I see the folders along the left side and then the list of emails indented. This is how I display them in Windows Mail and I just can't get anything more than a simple list of emails out of K-9, and it takes multiple key pressess to get that. I can't even figure out how to get a list of all the folders, like Draft, Sent, etc. The closest I come is "-NONE- (SENT)" and that really looks stupid to me.
I just can't help feeling I'm missing some in K-9, but my only real complaint with Email is there doesn't seem to be an easy way to "empty the trash", like there is in K-9. I did change the font and things and that helped. I also know my complaint with K-9 is pretty trivial, but for me it's enough to make working with K-9 a chore. I guess the visual difference is enough for me to deal with having to manually "empty the trash".
I'm hoping someone will "set me straight" and tell me just what attracts folks to K-9.
