It has likely been mentioned before but one of the only things this great game is missing is a screenshot key and a key to hide the UI elements. I understand that Steam has an overlay which supports it but some of us prefer not to use Steam.
Yeah, a UI toggle would be nice - for now the closest you can get for screenshots is by running at a high resolution with the UI scale set to minimum, then cropping.
MSI Afterburner and FRAPS work well for screenshot capture
