This is a simple mod to Zoom out to 0.1 factor for building Blueprints etc.
Default hotkey is: ALT + Z
This is the equivalent of running console command: /c game.player.zoom=0.1
NOTE: for Factorio 2.0 it does not allow zoom past "/c game.player.zoom=0.4", however on the plus side, the Map mode is far more useful, so a zooming mod is really no longer needed. Currently, this will not be updated. Thanks.
