Notepad allows creating session notes, descriptive text that is saved along with a session.
There are several ways to start Notepad, a tool in the Utilities category. Text and symbols can be entered directly or pasted into the window. Clear erases the window contents, whereas Close dismisses Notepad without altering its contents. Help opens this manual page in a browser window.
Session notes can also be created and/or edited within the File... Save Session As... dialog, which further allows saving a thumbnail image for the session. The thumbnail image and notes for a session can be viewed later (without actually restoring the session) by simply clicking the session file name in the File... Restore Session... dialog.
