I am leveraging the multi-page feature which is handy.

I can create additional pages by "drawing" them, then resizing them in the field at the top left.

However, there's no way, as far as I can tell, to perfectly align the boundaries of multiple pages without using snapping.

If I use snapping, then I can get the pages to align (cool), but then there is exactly ZERO space between adjacent pages. 

Ok that's fine.

BUT, there's a problem.

Let's say you have a 3-page document/design, stacked, one on top of another.

On the top page, you have a background box and maybe some other objects that overflow off the page and touch the page below it, OR, not even that, you have an object that is perfectly aligned to the bottom edge of its OWN page, but it happens to be adjacent to the second page (the one in the middle).

Later on, if I try to move the second (middle) page around by dragging (because I decided to reorder the pages), it will drag with it some of the objects that belong to the first page because they happen to barely "touch" the second page.

Here's a notion doc with screen shots showing exactly what I mean: https://www.notion.so/agentartifact/Inkscape-Multi-page-dragging-issue-2f29482b49ad4f4b97d42d05bbba5e49?pvs=4

So, I'm thinking, if there was a way to position a page, precisely, with coordinates, without using snapping, let's say, 100px below a different page, then I could avoid this.

The XML editor is one way to enter page coordinates.

Thanks for this reply. That is helpful. I figured out a work-around, which I explain in the Notion link, but this is just more direct.
