Back when LOOT was BOSSv3 beta 8, it could generate an image of the plugin graph used to sort the load order. This functionality was removed because rendering the graph image was slow, required the bundling of a separate executable, and the result too complex to easily glean useful information from.

An idea that came up was to save the graph data each time LOOT calculated a load order, and then use that data to produce an image that displayed the difference between the previously calculated load order and the newly calculated order.

As the difference would be much less to render than the whole graph, this should solve the performance problem, and the difference would be of greater benefit in informing users about what changes had occurred than the full graph.

Boost's graph library can output GraphVis files, and a quick search comes up with a bunch of JavaScript renderer libraries that could be used to produce images from them, which would be neater than using a separate executable (and could be done asynchronously with greater ease, so that the whole process was not slowed down).
