with much joy i want to announce the arrival of my MIT-licensed (free for all) 3D file and data management web-app, which is based on ThreeJS.
the first hurdle is now cleared : auto-arrangement of sub-folders in a tree data set (JSON input).
FYI : the rest of my websites CMS framework code is also MIT-licensed
demo at 3D file manager on nicer.app
i hope you can find a use for this, do email me at firstname.lastname@example.org if you want to share back
