As suggested by michael.grau86, i submit my idea here:
it would be great if one could draw freely on a draft. that includes logos, symbols, you name it, to be placed freely, without being bound to an edge. something as simple as windows Paint
so you can point out stuff, like directions of rotation, directions of flow, it might simplyfy exploded views, annotations, point out requirements. etc etc...
it would already be a great help if you could untie all available features from the edges, like leaders, surface requirements signs and what else is there
Thanks for your consideration.
