haha, no shame in using dirbuster, that was the first tool i used for this type of scan!
I don’t have any plans for a file tree at the moment. However, in all the terminals I use, you can click the URL and it’ll open a browser pointing directly at that page.
Also, if you use the -o|--output option, the final output is sorted by directory, so that may be an option that fits your workflow as well. It’s not visually a tree, but is still structured.
