Does Gnome Builder have a Source Code Browser?

Does GNOME Builder have a source code browser (sometimes referred to a Symbols View)?

I would like to see a panel (on the left or right) that lists all of the functions, global variables, class names, class methods, etc.

Below is a screenshot of a python file in Gnome Builder.

Currently, only a file browser is available in the left panel. Even using the “Select Symbol” button, I am unable to search for an existing method in the python file.

(I am running gnome-builder 48.2-2 in Ubuntu 25.10).
