When I made the switch to Mac and OSX, for some reason I stayed reluctant to trade my old trusty Thunderbird for OSX’ native Mail.app. But unfortunately Thunderbird doesn’t support the pesky Outlook calender invitations my company always spam me with, and I heard a rumor that Mail.app does, so I thought I had to give it a try then after all.

It turns out however, that I really, really, really, miss the three column vertical view from Thunderbird (and Outlook for that matter). For some strange reason Mail.app sports the older 2 column split mode… Fortunately, as always, Google has the answer. I quickly found WideMail by Dane Harnett, a modification to Mail.app that enables a three column view just like in Thunderbird. Also has many options to further customize the appearance. Thanks Dane!
