Hello! I love this tool. It's been an invaluable addition in my current project.
When I'm tracking down and trying to break dependency chains between bundles, it's very useful to know whether a bundle is referenced implicitly or explicitly (expanded or direct dependency) by another bundle.
I poked around in the source code, and I think I could add this feature. It's pretty straightforward to collect the data on the bundle (thanks to how the code is organized and structured). I think I could add this feature to the project, through a pull request, if it was desirable and useful.
I don't really know the best way to convey the "direct vs indirect" information, so in my case I just prepend a "+" or "-" to the bundle name. Or maybe split entries into "direct" and "indirect" tree items.
It is one piece of data that is in the build report but not this explorer tool.
