- Add volume control These volume controls are basically nothing more than sliders. They look terrible and hopefully will be as temporary as they are terrible. - Allow saving of specific non-user sources via obs_load_source and obs_save_source functions. - Save data of desktop/mic audio sources (sync data, volume data, etc), and load the data on startup. - Make it so that a scene is created by default if first time using the application. On certain operating systems where supported, a default capture will be created. Desktop capture on mac, particularly. Not sure what to do about windows because monitor capture on windows 7 is completely terrible and is bad to start users off with.
