Facing Pages for Spiral Binding
Having the ability to see multiple pages together, without them connected in the center would be helpful for creating things like spiral bound books. This would allow bleeds for each page, while still being able to see the pages together for layouts. This feature would come in handy for more than just spiral bound projects. It would be handy any time you need to see two pages together, while still having bleeds for each page.

Maybe an option for custom page offset and a option to use the current bleed setting (x2) so if a file has 3mm bleed then the pages sit 6mm apart etc and then and option for none.
2. Use current bleed setting
3. Custom gap
I agree with the idea of having the gap shown in normal mode and bringing the pages together in preview mode.
The current era of fast turn around, low volume digital printing has increased the need for this.

I suggest a page offset value from spine with facing pages documents.
Def. handy when there is bleed on what would be both the left & right of each page in a spread (but obviously not able to be set-up in the centre) & then the client rearranges pages - so that bleed on all pages thereafter need to be altered to the opposite side - VERY TEDIOUS (& FRUSTRATING) for long docs. We should be able to set-up a bleed for all sides which is viewable in Normal view but then the inside bleed disappears in Preview mode so that the pages are butted up against each other as it should be.
...And perfect-bound books.
This would also help for 3-hole punch documents.
