Improve Rhapsody connector routing via "connector points"

For "box" elements like classes/blocks/activities... there are many options available with grid lines, spacing tools, alignment... but when it comes to connector there is still a lot of manual work necessary to make a diagram "visually appealing".'

One source of this "uncleanliness" is that connectors connect to "boxes" at arbitrary locations - and cannot be easily aligned.

As example see the attached "ConnectorAlignmentX" screen shorts - depending on context the goal of the user is to have elements either explicitly connect at the same place - or explicitly connect at different places. Both cases require tedious "pixel-by-pixel" manipulation - and even then the result looks "unclean".

Proposed is to add "connector points" to the model elements - see the example of how it is done in the Web based graph editor gliffy (https://www.gliffy.com/) - attachment Rhp_SnapHandles.png .

There all UML shapes have typically 3 "magnetic" connector points at the each side that capture incoming connections.
(you can connect elsewhere if you really want to).
This allows to easily connect different model elements at a consistent location.

In addition in gliffy there is a central connector point with the semantic "use any and let the layout algorithm decide). This is also a very elegant way to let the user decide if he wants a fixed or flexible connection.

These connector points would be needed for all "non-line" diagram elements. For custom icons (like images) creating them automatically on the boundary box would be sufficient.
The number of them depends a bit on the shape - I would guess 4x3 for most elements and 4x1 for simple elements like condition connector, history, ... would suffice.
