Hi there,
You can customize the footer by going to Settings -> Client Area Templates, guides here. Our template engine supports plain text, HTML, and basic Twig syntax for added flexibility.
For custom pages, we recently released an early alpha version of this feature. Although it’s still in development, you’ll soon be able to create pages with custom paths like /~/{custom-page-slug}, and optionally add them to the menu. Each custom page will have its own template slot for adding markdown, HTML, or an iframe.
Stay tuned for more updates in Upmind monthly newsletter!
