The floatrow package provides many ways to customize layouts of floating environments and has code to cooperate with the caption 3.x package. The package offers mechanisms to put floats side by side, and to put the caption beside its float. The floatrow settings could be expanded to the floats created by packages rotating, wrapfig, subfig (in the case of rows of subfloats), and longtable.
