Now umbrello uses an intelligent behavior of associations during a rearrangement of widgets. However, this behavior may be sometimes strange, annoyed or even ugly. For example, let I try to compact diagram and make associations as short as possible. However, when an association becomes too short, the tool may unexpectedy rearrange its connection point, for example, reconnect from a bottom point of decision square (on activity diagrams) to a side point.

I think, may not be any more annoyment than a system, which makes decisions behind my back. IMHO, there is much more useful to make a set of connection points on a widgets, where I can connect an association. In more difficult way, there may be a mechanism of the definition of connection points, as, for example, this made in Visio. It is also possible to keep the intelligent behavior, when the user obviously starts the drag of an association from the middle of a widget instead of a selected connection point. This behavior is also well implemented in Visio.
