Several sources, one window
Every device gets its own column with connection, reading, statistics, trend and event log. + New source adds the next one, and the window widens to fit.
- Each column runs on its own background thread: a slow RS232 device never holds up the others.
- One shared CAPTURE button reads every selected column at the same moment. A specimen carried by three amplifiers is measured once, not three times.
- A switch per column decides whether it takes part in the capture.
