Right now when you draw a connector between two shapes, the developer must explicitly place the connector in addition to specifying the SiteIndex of the parent and child chape that it connects. Could you make GemBox.Presentation smart enough to only require the developer to specify the parent and child SiteIndex, and then _you_ correctly place the connector?
Currently, I have to select every object in my slide, then manually scoot them to the right pixel to force PowerPoint to re-draw the connectors. Not an ideal solution. :)
