Do you remember my posts about DGML? It has been some time since those posts, and even if the technology was great within the IDE, today is used only by very few extensions like the Architecture Explorer. So, today I find this extension for Visual Studio that adds some interesting options if you work with DGML.
First, save as SVG. It seems simple, but it is a MustHave!
Mode neighbor, in very large diagrams where you lose yourself in the meantime element, is very good to have a quick filter that only shows the nearby nodes.
Comparison of graphics. I have not ever used it, but if there is a comparison tool, that well already does begin it to take into account.
And much more… on the download link it is possible to see all the capabilities extension.
