Hi,

I'm willing to look into extensions later this year but we should then 
collect the wishes first. I know that for instance Tobias has some wishes 
with regards to straight lines [not that complicated] and i'm sure that 
Willy has some too.

while with half-grid steps I could put the intermediate link box 0
>(which btw shows as an empty dot; how to make it disappear so that

i see no quick hack [have to print the module] for the dot.

this looks doable and is mostly a matter of interfacing

horrible indeed but 1 / 2 / 3 / 5 connections as option are ok

i suppose that you looked into m-chart -) most is configurable in the mp 
module, so again it's mostly a matter of interfacing [and lazyness of me]

concerning changes in settings: you can change them in the flow and use 
grouping if needed, so you can have one connection with arrows and another 
with no arrows.

Also: for lovers of <angle brackets> i have a xml interface to flowcharts; 
combined with mathml and stepcharts and alike, this gives impressive chunks 
of xml
