It seems that when you connect one object to another, it will always draw one type of connector : a dark arrow.

I'd like to be able to select the default one (in my case not an arrow but just a link), right now I have to select and change it for each of them seperately, that is really annoying, and time consuming.

Another (workaround) solution would be being able to select only connections (instead of boxes), and bulk edit them. This would be handy in any case.

Finally, it would be great if instead of making a connection from an object to another we could also make a connection to a group of objects.
