I typically have a number of projects that I'm working on simultaneously - maybe a handful of journal articles on a particular subject, maybe a literary work and some commentaries, maybe a collection of tracking sheets.... If I have the files for just one of those projects open, it is easy to manage - navigating using the document tabs at the top. But if I have all of those open, navigating by the document tabs becomes pretty burdensome. One solution is to only have one project open at a time. But that means re-opening all those files individually. Having a way to open all the files for a single project with a single call, like this is suggesting, is really critical. I'm still working on ways to optimize this with the tools that are available in Goodreads for my personal projects. But for my professional projects, the ease of navigation from document to document in OneNote has trumped the superior document creation experience of Goodnotes, and I've switched for all projects that involve multiple files. This proposal is one way to work-around the problem of navigating between documents - there may be better ways (OneNote provides a sidebar for organizing and navigating multipe pages, for example). Putting all the files into one document and navigating through the document outline feels too burdensome, and it seems like large documents may strain the software (lag in writing). Please consider a way to easily manage collections of small related documents like this user has suggested!
