Thunderbird/Evolution quirks

[Michael Cronenworth]

My random thought for today:

Thunderbird is listed under the "Internet" sub-menu. Evolution is listed
under the "Office" sub-menu. Why are they in different places?

Ah...
mozilla-thunderbird.desktop:
Categories=Email;Network;
evolution.desktop:
Categories=GNOME;GTK;Office;Email;Calendar;ContactManagement;X-Red-Hat-Base;

As bloated as Evolution is, does it need 7 different categories?
