Yeah I did a really poor job with the discoverability there : ) Should I add an explicit icon to the toolbar maybe?

Btw, I created Shottr first and foremost for measurements, but tbh I'd say my main measuring tool in Shottr is still it's in-app selection. It's just more flexible, I can zoom-in, readjust the selection, use arrow keys to move or shift+arrows to resize, etc. But I guess this way of using the app is even less obvious and less used than the fancy auto-ruler thing : )
