Simple Distribution 1.0.0

Simple distribution lets you distribute objects evenly along an axis. It can distribute the centers of the objects evenly or keep a constant gap between them.

To use, select the objects you want to distribute. The objects are sorted based on the axis you select. The most negative object is considered the start and the most positive object is considered the end. The start and end objects won't move. They're used to calculate the distance between your objects which in turn is used to calculate how far each object should be spaced. In gap mode, the length of the objects are also taken into consideration.

There's a known bug where it won't work when the objects have their locations applied. That'll be fixed in a coming update.

Update: Blender 2.93 breaks the add-on. For some reason, it hides the buttons to select the distribute and sort axis. Still works in Blender 2.92.
