This week we try and allow pages to have snapping. Both to allow objects to snap to pages AND to allow pages to snap to other pages when moving them around.
Builds for the multi-page work can be found here: https://inkscape.org/release/inkscape-inprogress/ see MR 3486
Let me know your thoughts and as always thanks to my sponsors on Patreon, if you'd like to help and increase the amount of time I get to work on Inkscape, please consider joining at https://patreon.com/doctormo
