If it was possible to enable/disable sidebar in (AMS home, AMS category, AMS article page) would also be awesome.
Sometimes we can provide needed info in other ways somewhere. So no need to sidebar there.
This has been implemented for AMS Home, AMS Category Pages, AMS Article Page, AMS Author Page and AMS Field Search results Page (each has their own option).
IMPORTANT NOTE: Disabling the sidebar does NOT disable the sidebar blocks from fetching content if you have the sidebar block(s) enabled. This is so that those that want to use that specific fetched content in the View Wrapper template, they still can. If you are NOT using the sidebar content in alternate locations, then you should disabled all sidebar blocks when disabling the sidebar to prevent that data from being fetched (lowers the query count).
