I didn't think KSNIP was running because I couldn't see the system tray icon on macos running a dark theme with a light tray color.

All the other icons of mine (keeping you awake, openvpn, outlook, 1password, battery, wifi, etc) all switched colors to be visible. KSNIP was on the far left and I rebooted thinking it was broken. Upon boot thankfully I saw an icon gap (probably just app start order/speed) and clicked there which is when the icon became clearly visible.

I think it would be great if ksnip support dynamic system tray icon colors like other applications to do avoid this problem and be a bit better looking too.
