I have noticed for a few days that when I open a project, the folders on the left "pages" pane aren't maintaining my default to stay collapsed.

Thanks for reporting this, we will get this fixed asap.
Hey Justin, I looked into this, and the folder is expanding because it contains the current page. The other folders should honor your expanded level. Would you prefer the folders not to be expanded, even if they contain the current page (at least on initial page load)?
Personal preference would be to keep them all collapsed. As we continue to get more plan revisions/sets, I don't need the "old" one open. I would like to be able to go to the "correct' folder first and then expand.
