Thank you for your fast response. But more on this: If that is the case would you please grant a little bit of attention to this as a feature request.
Here's the motivation:
Considering there is currently no presentation functionality integrated in yEd; and taking into account that aesthetics, when it comes to projecting an elaborated diagram where printing is not practical is pretty important; that what is presented on screen marks the difference especially when the idea is the projection for the audience. I have realized that since their conception, the vast majority of diagramming applications are thought out to be used for the creation of graphical representations mainly to be used in the form of printed material. I have not found a diagramming software with the amount of flexibility that yEd provides for the user to that purpose. For some reasons, however, probably technical ones, the power on that flexibility goes against some aspects when it comes to its GUI; in this case the representation of selected objects. I would really like an enhancement in this area.
Please consider this as a feature request. Thanks.
