In more detail
Themescape has three ways to interact with a map: View for reading it, Work for changing it, and Present for showing it. Work mode is where the slow part of analysis happens. You can read a theme against its quotes, rewrite its working definition, star your favourite quotes and record how themes relate, without switching screens.
Changes made in Work mode last until you close the tab unless you save your progress, because nothing is kept in the browser.
In Themescape
Choose Work from the Interaction control. Work mode changes definitions, favourites and connections, and Custom placement arranges the views. Verbatim quotes are never altered. Saving your progress writes the changes to files on your own computer.
