App Window Size

Is there a way to adjust the window size besides the toggle button at the top? The window is small and difficult to use for me to begin with and clicking the toggle button just makes it even smaller and more difficult.

At the moment the app can only be changed with the toggle button. Could you possibly send us an email to with your screen dimensions and possibly a screenshot with Dubler?

The two sizes should be accessible for most people but if not any feedback is greatly appreciated!
