How about a Tab View?

Yes, I have several documents open at the same time because I have several projects going at the same time. Instead of having so many windows open and cluttering up the desktop (or dock), I would love to have all my projects tabbed in such a way I can see what is open.

This is actually a feature of macOS Sierra. Unfortunately, it’s not working properly with Scrivener 2.x, probably because of a lot of the legacy code that Scrivener uses to support older OSes, so the feature has been turned off (it wreaks havoc, causing views to disappear). It will be supported in Scrivener 3.0 (although we have no news on when that will be out, yet, other than that we are working on it!).

All the best,
Keith
