Flowlight 0.8.1

What's new in 0.8.1

• Flowlight stops working when you are not looking at it. It was rebuilding the live chart and the per-app list every second whenever a window existed — including when that window was minimised, completely covered by another app, or parked on a Space you had left. The work was gated on SwiftUI's onAppear, which only says a window exists, not that anyone can see it. It now follows the window's occlusion state, so a hidden Flowlight builds nothing and the menu bar rates keep updating as before.
• A blocking system call no longer ran once a second, forever. Settings read "launch at login" in a property's default value, and that expression re-runs every time the settings pane is constructed — which happened on every traffic update, whether or not Settings was open. Reading it means a synchronous round trip to the system service manager on the main thread. It is now read once, when the pane actually appears.
• Together these are the difference between an idle Flowlight costing a measurable share of a CPU core and costing almost nothing. If macOS had been listing Flowlight under "Using Significant Energy" while it sat in the background, this is why.
