Every feature GUI ran its own one second QTimer, read getState(), compared it against a remembered m_lastFeatureState and restyled its start/stop button when the two differed. The same twenty five lines appeared in each of them. Feature now keeps m_state private behind setState(), which emits stateChanged() when it actually changes, and FeatureGUI grows a shared updateStartStopButton() that restyles the button and reports an error state. A GUI connects to the signal and calls that, so the state is reflected as soon as it changes rather than up to a second later, and the per feature timers and m_lastFeatureState members are gone. FeatureUISet disconnects the feature from its GUI before the feature is deleted: QObject emits destroyed() before dropping its connections, so a stateChanged() emitted from the feature's destructor could otherwise reach a GUI that has already deleted its ui object.

Ancillary projects
- SDRangelcli is a web application that can be used to control a headless (server flavor) instance of SDRangel. It can also be used as a remote control for the GUI flavor.
- SDRangel-Docker is a collection of Docker files and scripts to facilitate building and running SDRangel in a Docker container. Works for either the GUI (only on a Linux host) or the server.
