To further distinguish this excellent application from alternatives, integrate Chromecast support, to display videos on the television, and use higher end speakers (often connected to televisions) for audio media. The Chromecast SDK is free, and SMPlayer developers are clever, ambitious non-conformists, a perfect combination. Chromecast integration would be a significant improvement, well received by current users and a powerful reason to switch to SMPlayer.
Thank you for considering my suggestion.
