Rename Multiple Ships at once:

Reassign behavior / default behavior to multiple ships at once

Group ships into groups for better overview and not only for fleets

Drag and Drop functionality for fleet assignments

Drag and Drop functionality for personnel reassignment

Reassign multiple crew from multiple ships to crew of a new ship (ideally also by drag and drop)
