Hi, yep :-)) this will be added too! I hate using my mouse for the 80%
most likely tasks.

BTW: Anyone working on a grid system? I know there were some efforts...

Right. But the grid system needs to be easy. Why do I have mark columns,
click on an edge to get a perfect width layout? That's what I want be
default...

Ah, now I got what you mean. It just shows contact/company because it's
the first entry ;-)). It doesn't have any semantic meaning in this case.
Perhaps I should add a "select BO" entry.

Really? It could be a workshop-event, a product etc. For example: You
hear/read about MikroTOP and know you want to know what this is. You
know that you got this information from me. With RFM you would connect
to my data-graph and now you have to ways to get to MikroTOP.
1. Select my person and look at the graph. Maybe somewhere you see the
MikroTOP node.
2. Hack in MikroTOP and see what you get. Than you get the information
that it's a project. From there you can go on and build up your
understanding about MikroTOP. It's like discovering new information.

That's a good idea. And yes I will add it. But it's an other way to
work. This is more like the "normal" database pattern.

Hmm... I'm not sure if using three panes is really necessary. You have
grid, data-record, graph. Might be a bit complex to handle. Maybe in an
advanced user-mode.

Why would you show the employess of the company and not the projects of
the employee? The system can't know what you want to see...

It's more powerful if you need to see the big picutre. I'm not sure if
it's powerful for transactional systems. Try to build the examples you
see on the screenshots of RFM with a relational model. Than try to get
the same information level when looking at the graph. Than you will see
what I'm talking about... Robert
