Hi, since the Conveyors in the Conveyor Module are able to do a lot of stuff only by dragging around (e.g. connect to other Conveyors, change size) it happens very often that connections (Transfers) are created or droped away accidentally while working on a model.
Normally we are just creating the layout of the conveyor system and after this we implement the logic (e.g. Photo Eyes, Decision Points, Connections).
So I think it would be helpful to have a "switch" to turn on/ off the edit mode of the Conveyors. So if the edit mode is turned off, the layout can´t be changed (accidentally). Nevertheless adding Photoeyes or Decision Points could be allowed in the turned off edit mode.
