Less automatic alerts please! Let us be able to use sirens+circuits to send local and global alerts for things we care about - like biter expansions near our bases.

Thanks a lot for adding this! Btw: Factory Managers can easily change these hidden settings by clicking with Ctrl+Alt on the Settings button.
