Comment 5 for bug 754095

Ahh, I see now that 'favourite' refers to any program with an icon on the launcher. I have no problem there. Thunderbird was already on my Unity launcher in 10.10 (netbook edition) and persisted after the upgrade. Naturally, this is how I choose to launch the program, but it would still be nice if the dash also pointed to Thunderbird as my default email program.
