Can be useful, but there are some glaring mistakes.
For one, repositioning an object over a large distance is very inconvenient without the ability to enter numbers manually or a "bring to player" option.
Two, the list of root gameobjects doesn't seem to update correctly. Gameobjects added by mods are missing until I search for them. I'd recommend waiting until all mods are loaded (with the ModLoader.allModsLoaded property) to populate the list, and also adding a refresh button that clears and repopulates the list.
