Testing v7 little bit. I am glad to see there are some improvements in object attributes.
Would it be possible to add even more features to this? Like proposed in the pic. The point is once there is room for adding formulas it will be really powerful and the model can turn to nice model database.
Besides things in the pic very nice feature would be conditional attributes. For example if you created key/value objecttype/concrete there would be new attributes automatically created for this unique key/value pair.
