notificationsscreen-sharing
I'd like to never show ANY notifications if I'm currently screen sharing to prevent those awkward moments where I forget to disable them manually and run the risk of someone IM'ing me something inappropriate. Notifications should be automatically disabled when I start screen sharing and automatically re-enabled when I stop.
Is this possible at all? Even if it requires some development?
This feature seems to now exist in Apple Screen Sharing Version 1.5 (481.1)

Or View > Show Toolbar and then select Use Shared Clipboard
Reconnect the monitor. On the Mac Pro, set the resolution to a lower setting (as a test to the lowest possible one). Then try again with the monitor disconnected.
If it works, you can then increase the resolution.
I've had similar problems happen several times over the years. Sometimes connecting a display adapter to the video card (even though it is not connected to anything) will fool the video hardware into working properly.

You didn't mention the OS you're using so for this answer I'm using 10.12.5.

You can option+click on the 3 lines for Notification Center in the menu bar:
This will silence any notifications that use the Apple system for notifications. To put notifications back to normal, option+click again.
This doesn't silence any notifications that don't use Apple's system. To silence those, you'll need to turn them off at the application-level.
