Feature Request: Add Arrow that Can Be Placed in the Middle of Spline

[makamto]

The ability to place an arrow in the middle of a spline would enhance the functionality and versatility of the application, particularly for users who work with visual representations of data, diagrams, or design elements. This feature would allow for clearer communication of directionality and flow within a curved path, making it easier to convey complex ideas visually.

Thank you for considering this feature request, and for your continued efforts in making this amazing application a valuable tool for users.
