This mod allows for fine-tuning position and rotation of parts in the editor.
Includes ability to scale(resize) parts.
Now with experimental multi-part mode
Tab for multi-select, then X for multi-edit (multi-select and multi-edit are separate modes for simplicity), or use the GUI button to cycle through them.
Multi-selected parts will all rotate on the axis of the first selected part (unless changed in the mod settings, which require Mod Settings mod).
Scale does not move multi-selected parts when scaling them.
Multi-select selects things, then when things are selected you change to multi-edit to actually adjust them!
Thanks to @Skua for the icon :)
