The left pane contains several sections to view different pieces of data about Polynote.
The about menu contains information about your instance's version and most recent server commit.
The hotkeys menu contains a list of all supported keyboard shortcuts in Polynote.
The preferences menu contains two sections - UI preferences and storage.
The preferences menu is where you can customize your vim, theme, and notifications preferences as seen below.
Note that these preferences are stored in the
browser. You can clear these settings by using the
Clear All Preferences and Storage button.
The storage menu displays key-value pairs of all the data Polynote it storing in your browser's local storage, and provides easy access to wipe that data.
The open notebooks menu contains a list of all open notebooks alongside their kernel status. A notebook is considered open if any client has it open, or if there is a running kernel associated with it.
This means the menu can be used to list notebooks not open in this particular browser, or to find running kernels you might have forgotten about.
Note that the server keeps a notebook open for 30 seconds after it was last closed.
The client-side backups menu contains a list of all the client-side backups that Polynote occasionally creates of your notebooks and stores in your browser. This pane may take a long time to load if you have many backups.

You can also print these backups to your console in JSON format, or clear all previous backups. Unfortunately,
there is no easy way at this time to recover a backup - you will need to manually parse the JSON (which is not in
The state inspector menu shows the current state of the server, as well as each notebook you have. This is mostly useful for debugging purposes and reporting errors.
