A friend, new LO user pointed to me that Writer doesn't have a way to insert a connector to create flowcharts or other graphical representation that requires this function.
In my particular case, I usually use LO Draw to do any kind of diagram and then import it into LO Writer, however, having different workflows is important for casual users for different reasons.
• Writer introduces basic drawing tools, including shapes for flowcharts. This is incomplete without adding connectors 
• Other popular word processors include connectors
• Casual users only use a word processor for this work
• A casual user may not install LO Draw
I really don't know if this is a design decision, but in spite of not being directly affected, it can be seen as a bug to use another application in the same office suit (Impress or Draw) to only add connectors to drawing objects.
 An alternative workflow can be seen in GDrive, since in order to insert any type of drawing, a new window opens with Google Draw instead of offering drawing tools in its corresponding Word Processor.

I noticed that the arrow toolbox has been added in the development version Bug 101390 , so I imagine it is possible to do the same with this option.
We have lines, arrows and curves in Writer, why not connectors?
Please give the user the connector functionallity in writer it's always strange why in one office suite the different apps work different.
