The Add Page dialog box offers a few variants of lined and gridded pages, and three color. But it could do more. Patterns, colors. I’m using a notes book created in Xodo and made some scripts to create pages like single-color, checkerboard pattern, gradient, hexagonal grid etc., even a calendar. (I’ve added links to the scripts, but the forum engine didn’t tolerate it so the post was lost.) But some of these may be included with Xodo IMHO.
