Good app but not scalable :(

I downloaded this to see whether or not it would meet my needs before buying the paid version. I like it, but I can’t get around the major setback that prevents me from buying the paid version. Namely, the window goes full screen (like many games) and there doesn’t seem to be a way to scale the window size down. Maybe I’m missing something, but dragging the edge of the window frame does not allow scaling in the way that OSX windows do by default. I’m a digital artist, so this is a problem for me because I was looking for a good anatomical application to use as reference on occasion while drawing, painting, or modeling in Zbrush. I suppose I could move the app to a secondary monitor at my workstation, an iMac, but I do not have this luxury while working on the go with my MBP.

If the developer is reading this, please add the ability to scale windows— or tell me I’m an idiot if I didn’t see something obvious lol. That is the only thing preventing me from buying your paid apps.
