There are two ways to access the source code for an app or a particular proc. The Details pane includes a URL link to GitHub. Clicking this link opens the default browser directly to the app page inside GitHub. The source code of individual procs can be accessed from this page.

After an app has been installed, the proc names become hyperlinks. To view the source code, click the proc name, and select View Source Code.
Note: The Tcl Store does not track the procs dependencies. Only the content of the selected proc is displayed in the source window, not dependent procs. The full app code can be browsed from GitHub by following the app's URL.
