Editor view limited in dual pane

[gravelfreeman]

There is currently a lot of wasted vertical space in the editor when using Dual Pane mode.

Roughly 90% of this area is unused:

This isn't really an issue in regular Read/Edit mode because the header disappears as you scroll down.

I understand that, because of how Dual Pane mode is designed, it probably wouldn't make sense to change the scrolling behavior or rearrange the entire editor specifically for that view.

Instead, I suggest adding a global Focus Mode that would automatically rearrange the interface like this:

The AI Assistant and Outline could still be pinned, just like they can be currently:

The sidebar could automatically appear when hovering over the sidebar area, then hide again when the mouse leaves:

Focus Mode could be toggled with F11, or through an icon here:

While we're at it, I would also move the controls that affect the editor/interface layout into the bottom-right interface controls, including options such as Width and Dual Pane.

This would also help reduce the number of controls currently displayed in the top toolbar.

Focus Mode should be application-wide rather than page-specific. Navigating to another page should not disable it. It would remain enabled until the user manually turns it off.

@timothepoznanski Awesome! Can you make the focus buttons on/off? I don't like that it's cycling. It falls in the less is more 😄
