[enhancement] Better layout algorithm

[thien-do]

There was this another issue in the previous version (which I have previously installed) where the line was overlapped by table.

Maybe it might have been fixed in the newer version.

At the moment we choose to place the Tables over the References.

As far I understand the canvas (well, I don't even know how this plugin is build) has infinite space so just push the table bit further away so that the references doesn't over lap the tables.

And I mean by the above image.

NOTE: The above image was taken after the table arrangement was done by plugin automatically, I didn't change their positions.

Not this 👆

This is a very reasonable approach :D Unfortunately our current "layout" algorithm is not quite as good. Let us improve it. You are right that the layout should put the tables to minimize the overlaps
