Mingo supports multiple windows at a time - a workspace. Each connection and project has its own workspace. You can switch between workspaces with the workspace selector at the top of the sidebar.
Mingo's sidebar is the main navigation. It contains:
Allows selecting the connection / project you want to work with. Your entire view (Mingo's window) is focused on the workspace you have selected.
This is a tree view of databases and their collections. Use right-click on a database or a collection to show the respective context menu.
If you click on a collection, it will open a new tab.
Mingo shows basic collection stats if you point the cursor at it.
Tabs in Mingo work the same way you are used to from a browser. You may rearrange tabs (drag & drop or keyboard shortcuts), close, reopen closed tabs or close "other" tabs.
The following types of tabs are currently used in Mingo:
Tabs are separated into views (such as "Documents", "Aggregator", "Indexes" or "Export" in case of a collection tab).
Mingo has lots of features and these are mostly hidden to keep the UI clean. Most features can be found using the context menu (mouse right click). The context menu works as usual, showing options for the item you click on. Such items are database or collection (in the side bar), a document, a document field, etc. So, if you want to "do something with a document field", open the document and right-click on the field in question.
When you open a new tab, Mingo's finder will pop up. It let's you open collections or databases swiftly. Just start typing the name of a collection, for example, and Mingo will give you suggestions.
Use up and down arrow keys to select a collection and left or right keys to choose a view. Enter to submit.
