Make the Layout Responsive!
I'm super glad you've made a Mac desktop app. I'd like to have it docked on one half of my screen though, and the layout could be improved when in that configuration. Perhaps have your control panel shrink down into a button when the screen gets small enough? Keep up the great work.
Very impressed with the app, works well. Just a heads up;
Message boxes shouldn't have a set-width, I think they should have a min-width but otherwise fill 100% of the window. I've done it in the dev console and it looks great. Also maybe tie view widths to the text and line-height so the text also scales appropriately. Not sure how much of your userbase is using IE or anything but I think some of the styling could be just a little better. Otherwise very impressed!
Both the website and the Windows Desktop app would benefit from this too! Users should be able to put their window on half the screen and still be able to use the app effectively.
