The moses tool to create more space in a definition is useful but maybe it can be improved
Expand and contract. Oftentimes I need to remove space in a definition. Maybe Moses could have both functions depending on the direction. alt + drag to the right adds space, alt+drag to the left removes it?
Local expand and contract. When dealing with large definitions you sometimes need to affect local parts of the code. Maybe there could be another modifier to add and remove space only to the visible portion of the definition.
