In Mongo Management Studio each collection will be opened in a tab. If you click on a collection in the left navigation tree, a new tab will be opened or a existing tab will be selected when it is already opened for the collection. But you can also explicitly open more tabs for a collection. To do this click with the right mouse button on the name of the collection in the left navigation tree and select the context menu "Open new tab".
Each tab has a title consisting of database name and collection name (e.g. blog.posts). In addition, a coloured bar is in the title of the tab. This includes the color of the server connection, to which the collection belongs. Thus one can distinguish the tabs, if you are connected to multiple MongoDB server instances.
If you click with the right mouse button on the title of a tab, a shortcut menu appears with the functionality to either close all other tabs or all tabs.
