I always made extensive use of the old layout adjustment feature in 'margins and columns', yet the new 'adjust layout' gives inconsistent and confusing results, resizing objects that never used to get changed.

It's gone from being very useful to a liability.

For me it was great for resizing the main text frame on multi-page (100s+ pages) books, but leaving the objects pasted into the text frame alone (figures, etc). Also moving page numbers aligned with margins, but not changing the sizes.

The new feature stretches and distorts carefully measured objects/figures, changes anchored object settings (at least, things move about incorrectly without the numbers updating) and causes other weird behaviours.

I'm not sure if this is the right bug category, but when trying to view spreads, no matter what view option I pick, the pasteboard is aligned right only, with lots of extra room on the left. If I scroll all the way left, the left edge of the pasteboard is about in the middle of the view area and if I scroll all the way right, nothing past the right edge of the pasteboard is visible. It should be the other way around if not centered, because at least then, all my tool panels wouldn't cover up what I need to work on, on the right side. My only work arounds are to detach and move the tool panels, or zoom in enough that panel doesn't cover up my spread, or make a giant pasteboard so that there is enough extra room on the right side. All of which are annoyances that 'bug' me. ;-)
