Default "project" on open?


I’m new-ish to Scapple and I cannot find a way to do what I want to do. When I open Scapple, it opens an empty Scapple document. But I’d like it to open one of my three current Scapple docs. (I’d also like to put those three docs on my taskbar for a quick open option, but I can’t figure that out either (yet).)

As I said above, I’m really new to Scapple, so I hope I haven’t missed an option somewhere. I’m running version on Win 10.

Thank you,
