Dimension lines

While my previous post gets reviewed to approve being posted (it had a link in it)...

I have created these in Miro, the main thing that would make life easier is the extension lines that sit at the end of the arrow heads. In my example below the extension lines are just separate lines sitting at the end of a line with arrowheads. It would be great to have a line ending/head that ended in a arrowhead with an extension line included.

For Miro that means its just one more line head type i.e. not a substanial change/orphan feature. But for those of us who use dimension lines it would mean that we could create a dimension line with one object instead of three.

The angle of radius lines are also a little difficult in Miro e.g. the 90 degrees dimension line on the right. If we could somehow have the line snap to a circular, or perhaps its another line type.

Currently we have straight lines, branched lines (my words), and bendy lines. How about a circular line, like a bendy line but it enforces a fixed curvature between the two points at either end of the line

To help with what an extension line is
