In the Unity applications lens, there are dozens of applications listed that are also listed in system settings menu. Considering the system-settings window can be reached by clicking on the upper-right-hand-corner drop down menu, as well as from the "system settings" application launcher in the Application lens, is it really necessary to have all of those same programs listed in the application lens? There are over 20 duplicate and un-needed applications cluttering and getting in the way of the applications that people 'want' to get to.
Also, in the application lens there are logout, lock screen, restart, and shut down buttons present. Why is this? Those options are not even applications....having them in the applications menu makes it seem as if "shut down" is a program that can be run, rather than an integrated part of the operating system. Basically, these 4 options have no place in the application lens, as they are not even applications, as well as already being listed in the system drop down menu (in the upper right hand corner).
If the end goal is to make unity more user friendly and more organized, I just listed 27 items that can be removed from the application menu with, from what I can tell, no adverse consequences.
I am using the 12.04 alpha, but I can confirm that this is also present in 11.10.
I definitely think that this is an issue that should be fixed for 12.04 lts. This is one of my biggest annoyances with Unity, and I do not believe it would be that hard to change. Am I the first person to notice this issue, or are the shut-down/
