Unfortunately it is only partially implemented at this time.
You may currently zoom from 20% to 200%.
- Distortion
Currently there can be some distortion when using the Zoom feature. This will be fixed as the feature is fully implemented. - Mouse Dragging
Mouse-dragging of units does not yet work while at any zoom other than 100%. In v1.0 it will work as long as Snap-to-Grid is disabled. - Mac Scrollwheel Zoom
Mac scrollwheel support is not curently available in Director, so heruca will not be able to add it to BRPG for the time being.
It has already been added for PC users. - New Hotkeys
The next version of BRPG will require that the CTRL key be held while pressing the Up or Down Arrow key to zoom.
