Connect to an Edge (not connection point or object) to ensure connection lines stay straight

Is your feature request related to a problem? Please describe. Drawing block diagrams that have lots of lines going into a box (etc.) it's a pain to get all the lines straight.

At the moment, you can connect to either the entire object, or to a point on the edge of that object. But...

Describe the solution you'd like It would be brilliant to be able to be able to drag a line onto a side of an object, and the line just goes straight (horizontally or vertically) into it. Here's a mockup:

Then... with these three circles connected to the bottom edge of the box, I could resize or move either the box or any of the circles... and the lines would stay perfectly straight... until they moved out of bounds of course, at which point the line would curve as required.

This means that diagrams would stay beautifully ordered, without having to line up connection points perfectly.

+1 This is my number one gripe with Diagrams.net today. Straight lines from box A to box B (constrained to 90 degree angles), without being forced to use blocky lines between randomly-placed 'connection points'.

This seems to be implemented with the addition of these two new line types.

That said, it seems that the tooltips are wrong (they're all set to say "Simple").
