Prettify Workflow instead of Snap to Grid

[irgolic]

I feel like snap to grid isn't too useful, its role could be better fulfilled by a prettify workflow button.

Describe the solution you'd like
Upon a click of a button, the workflow is rearranged into an aesthetically pleasing configuration, as such:

Actually, I don't like the prettify button. This should be like Illustrator's "Snap to object". When you drag a widget, it would snap to position in which the connection line is horizontal, or the widget is horizontally/vertically aligned with other widgets. The former has the priority.

We don't even need a checkbox for this functionality. It could be just enabled, always.

It could be just enabled, always.

I think that would satisfy only us, super OCD people. I am not sure this is useful when building complex workflows where many connections overlap. I've seen such workflows and they would probably grow even bigger with this option.

Of course. It's far from a must-have.

I think it's nice to give the user agency over where nodes are placed. The prettify feature should serve the same purpose as a code reformat action in an IDE.

I imagine it'd also be useful for creating examples for screenshots.

This is a canvas issue. Continued in biolab/orange-canvas-core#53.

A button for recomputation of all widget positions is what I meant.

I'd like to take this

and with a click of a button, produce this

Why do you believe such a solution to be infeasible?

[janezd]

I just wanted to say it's so difficult that it won't be implemented. Plus, I suspect that automated positioning won't always give the desired results. I think that snapping is easier and also more useful. But of course I wouldn't object to this solution, if you (or somebody else) implements it.
