I used Thunderbird a lot when I was still on Windows, around 2007, and loved it, both for email and as my RSS reader. By the time I moved to linux somewhere in 2009 it started to feel... stuck. I needed calendaring, and Lightning barely worked with caldav. The contact management system in Thunderbird was always bad, but when trying to integrate with carddav (with SoGo at that point) at best it was problematic. Then the whole Thunderbird project seemed abandoned at one point, only to pick up Firefox's new engine and layout ideas which killed off a lot of plugins. I moved to Evolution, and for linux, I don't think there's a smoother option out there with the same level of features. Unlike Thunderbird it finds my carddav & caldav server from PTR records and configures the whole thing correctly, working, with one "Collection Account", plus it never had the 2GB file size issue I hit with Thunderbird that made my life quite miserable in 2009. Anyhow: congratulation, it's a lot of work, and the team can now close a feature request that was open since the beginning of time (wide view), but I'm done jumping from software to software as long as the current one works as expected; for me, that's Gnome Evolution.
