Multiple widget orientation modes
Now widgets are always oriented from left to right (inputs on the left, outputs on the right) When workflows become big it becomes impossible to nicely arrange widgets. It would be very great (unique - I've never seen this before in any such platform) feature if one can choose layout of each widget (left-to right, top-to-down, right-to-left, down-to-up) Otherwise (without this feature) layoting engine needs to have some way of modifying connections - manually drawing connections
