MindMup now makes it easier to style large maps automatically, using the theme editor.
Previously, users could automatically style the root nodes and the first four levels, but now you can apply automated styling to deeper levels of larger maps. Here is how to add more styles to your maps:
First, open the theme editor using the View - Customise Map theme from the application menu.
Next, click the “Add Level” button in the bottom right corner of the theme editor
This will add customisation options for one more level. You can repeat the process and add as many levels as you like into the theme editor.
