How can I sync diagram during active class development?

[Jofsey]

When I write a class and it became too large (20+ methods), I can't no more keep them all in mind at once. But now with this plugin I can. And it's amazing.

I create a diagram, do some mouse dragging to regroup methods according to my understanding, and when it's done, I can keep the whole picture at once, and I know what to do next. I add/delete a method and I want to sync, but the only option here is to create a new diagram, which means all method's positions will be changed, and it's a mess again.

Even if I don't move methods by myself but just use any of layouts, a small refactoring can change positions drastically.

If there is no features that can help me now, please consider this post as feature request for:

1. sync button / autosync
2. keeping elements' positions during method adding, deleting, renaming, etc.
