I guess you know how this works. You need to exert a certain speed/power to hit the corner. That will also solve some annoyances that you could open activities by accident -although the trigger is sensitive enough.
It will work for more than one monitors, and if your XServer doesn’t support it, there will be a fallback to the previous behavior, both for Hot Corner and Message Tray.
You can set your very own values at
const MESSAGE_TRAY_PRESSURE_THRESHOLD = 250; // pixels const MESSAGE_TRAY_PRESSURE_TIMEOUT = 1000; // ms const HOT_CORNER_PRESSURE_THRESHOLD = 100; // pixels const HOT_CORNER_PRESSURE_TIMEOUT = 1000; // ms
Ohh by the way GNOME Shell 3.7.91 is out!
