Pages improvement

I’ve just downloaded the new update, and I’m enjoying exploring Pages! I have a few questions and suggestions:

1. Setting a Page as the default tab: Posts still opens by default when entering a space. I was told the next release would let us change this. I’ve created a Page called “Main” that I’d like users to see first when they enter the space. Is this possible now? Couldn't find a way to redirect a page to default.
2. Page width: Pages seem to reserve room for the right-hand widgets, even though widgets such as “Recent Activities” don’t appear there. Could Pages use that empty space for a wider content area?
3. Shortcodes and embeds: It would be great to add shortcodes or embed content from other Fluent products, such as FluentCart, directly within Pages.

Thanks for your feedback! If anyone knows how to make these tweaks using code snippets, I’m all ears!
