Maybe I'm doing something wrong, but shouldn't the commands (run separately)
notify-send -t 1 "test" notify-send -t 1000 "test" notify-send -t 10000 "test"
Have different timeouts? The first being nearly instantaneous, the second one taking 1 sec and the third 100 seconds. In all cases it seems to take about six seconds.
Is there a way around behaviour? As the developers label this as a "feature" instead of a bug, I would like some alternatives.
