Using the layout tool Notion allows you do drag staves vertically to adjust spacing say if you are trying to squeeze one more staff on the bottom of a page, as well as make measures wider or narrower to squeeze in another measure on a staff or make one wider. The problem is when you no longer need it that way it won't go back to the default and you have to manually drag everything to where you think it should be and try to get the staves ending in the same place. Also when you've squeezed an extra staff on a page sometimes staves jump ahead of other staves so they are out of order. Notion needs a reset button that will put things back to the default spacing before manipulations with the layout tool. I hope this will be in a future release.
