New navigation
Those who previously worked with IPython Notebook probably know how it is not convenient to work in the main window of the program, because all the * .ipyb files should have been located in a specific folder and the user could not move around in her tree.
With the release of the new version, this flaw was finally eliminated and now we can navigate through folders of different levels, which is undoubtedly more convenient than it was before.
Modal interface

- Edit mode It is highlighted with a green frame and you can get into it by pressing the
enterbutton.
- Command mode It is distinguished by a gray frame. In this mode, the cell is not available for editing. To change its contents, you need to put the cell in edit mode.

Export working notebook
Another great innovation is the addition of export formats to the console.
Users of the first version remember that there was only export to a python file ( .py). And in order to overtake the working console in the html file * it was necessary to go to the console and execute the nbconvert command with hands.

Interactive Widgets
Widgets allow you to create high-level interfaces for Python objects, such as functions. There is a standard set of widgets included in the release, and there is also an API for creating them. More information about the widgets, as well as examples of their use can be found in the documentation.
Enhanced security
In version 2.0, the console starts in safe mode . In this mode:
- Trust is determined by the parameter at startup
- Untrusted HTML is being cleaned up.
- Untrusted javascript not executed
- In cells such as
markdownJavaScript and HTML are considered not trusted if no parameter is defined inmarkdown1.
