Center and Arrange is a good option for "quick and dirty" placement but it doesn't always accommodate the geometry of the parts being printed.
The following suggestions may help.
1. Auto-Arrange Accounting for Model Geometry - Functionality similar to center and arrange that accommodates geometry. Placing higher edges closer together and auto rotating parts for efficient printing. If you're printing door stops for example, you would want all of the highest points to center back-to-back to allow the final layers to wrap up more quickly reducing travel time. If the doorstops were arranged with the final layer height being equal, you could arrange them into a square/pie shape to reduce print time or better utilize the print area.
2. Snap Arrangement for Manual Placement (Translate Model - W) - Give a snap to grid/ruler option to allow easier manual placement. This would keep axis aligned more easily as well to further keep print times in check for multiple objects. It also prevents the need to open the model menu and manually type in a particular axis across several parts.
