Location of "New Issue" menu item
Logically, the "New Issue" menu item does not belong to the main-menu, but to the sidebar within the Issues category (New Issue, View all issues, Summary)
As this is the main feature of Redmine, it is obvious to put it in the main-menu. Additionally it would be nice to have it in the Issues category too. A lot of our users where looking for this item in the sidebar.
