If I remember right, then your complaint applies to Cinnamon up to version 1.4 UP3. This was very likely the reason why I used Synaptic
and installed the package alacarte
. Doing so will bring back Preferences
=> Main Menu
(hm German title), might be Menu Layout
(in genuine English).
I am not quite sure how Cinnamon 1.6.7 behaves with respect to Preferences => Menu Layout, because alcarte had been installed by the time I updated to Cinnamon 1.6.7.
