On MacOS, please consider the following, or at least make them options:
1. Notifications should use the standard Mac notifications instead of custom ones.
2. Notifications cause dock icon to bounce continuously until addressed.
3. Notification appear regardless of which virtual desktop is visible.
4. Notifications remain visible until addressed.
Any or all of the above would improve notifications immensely. I'm currently missing messages because the notifications are not seen....forcing me to continually monitor the application manually.
