I’d love to have separate sidebar groups for saved searches and projects. My lists are very long, and although save searches have a prefix this is confusing. If the sidebar had two groups which could be individually displayed or hidden as in many other apps’ sidebars, that would be great. I wouldn’t even need a prefix or italics then.
Edit: Also, now that there’s drag and drop for projects, it would make the behaviour of sidebar entries consistent across each group.
Edit2: The project button also gives you the whole list. For the reason mentioned above, I’d prefer to have to separate buttons for projects and searches. Saved searches could also be included in the drop down menu of the search field.
