After launching the desktop app on Mac OSX, the application window always resized to fit the whole screen and has to be manually resized.
This is something I have always been annoyed by since the desktop app is around. I prefer my apps to take up only a fraction of the screen to be able to see other things (e.g. browser windows) in parallel. It is not a huge issue, but at least on my part it is a bad user experience and I hope to see it fixed.
